It's a 7.62x25 subgun made from a damaged AKS in the sandbox. He chopped the receiver and welded it back together. The bolt carrier was also shortened.
The man holding it is a somewhat notable gunsmith who repairs weapons for citizens there to use for self defense. The Firearm Blog, I think, had an article about him a few years back.

Looking at your pic more closely I cant see any seams between what would be considered the upper and lower recievers on the bottom 3 guns, also given that they have a round upper reciever this could mean they are actually stamped and bent rather than constructed from common steel tube.

Despite the potential usefulness, I've been reluctant to bring up details of homemade guns in gun control debates because I know nothing about metalworking, and I can't really tell how technically difficult a lot of the plans that float around, such as the attached, actually are.
Theoretically, could an average person without prior experience go out and buy the tools, watch a few youtube tutorials, and after a bit of practice have a reasonable chance of making something functional without maiming himself? The welding in particular I have no idea the difficulty of.
And for a typical hobbyist, how many man-hours would one of these things take to make? For the purposes of debate, if some criminal organization decided to have one guy in a workshop making these like a full-time job, how many people could they arm and how quickly?

Steel can be found on that shape and cutting shapes is viable even with a fucking vertical drill (or a vertical drill rigged into small milling machine).

That's not 5.56 NATO. It's either 7.62 NATO, 7mm Mauser, or 8mm Mauser. 7mm Mauser was more common down there because of all the Mauser bolt action rifles they used to have. The gun is straight blowback and was used by a gang. It should have a roughly 8-10 lb bolt to operate safely and the receiver does have enough room for it in the back end but they may have been using something as light as 5 lbs.

When I was modeling the Luty designs I got to thinking about the tools that would be available to most people and the tools needed for this kind of work.

Here's a section of the bolt assembly showing the firing pin. The pin is made from 2 separate pieces, a standard headed pin with a spring pushing it back and a larger diameter rod cut to length with a bit scalloped out for a screw to stop it from backing out. The bolt handle will be the firing pin stop.

That's only marginally better.
You could easily move the mainspring so that it sits above the barrel and the bolt pulls the guide rod to compress it, and then have a separate guide rod and spring for the striker which sits at the back of the gun.

On the subject of rifling, would it be possible to bypass the problem with the usual blowback SMGs like the BSP 9 by using a pre-made 9mm AR barrel?
I know the cheapo SMGs lend themselves more to short range spraying and praying, so rifling might not be all that big an issue, but I still think a proper barrel would be a great improvement. I'm pretty sure that you can buy Sten barrels and the like for not too much cash, but AR barrels are far more ubiquitous.

A $5 demilled barrel can yield 3+ (depending on length and location of holes) rifled barrels of high steel quality. The AK barrels have good dimensions for rechambering to .32 ACP. You can also get FAL, Galil, and other assorted barrels on the cheap as they're all shittily demilled.

Short barrels can be drilled with a simple twist drill and reamer, if you want to step it up a bit you could even make your own rifling button since with short barrels you can just press it through on a commonly available hydraulic press.
It doesn't solve the larger concern of ammo though, ammo is still controlled and most creators of these designs assume you can get a hold of it. Luty got put some thought into this by making ammo with brass tubing with match heads for powder but its not exactly a great solution, with the process taking considerable time and producing sub-standard ammunition.
I have been thinking about this over the last few days I am starting to believe that a truly successful design has to be a complete package. Gun, dies for drawing brass cases, tooling and guides on how to make basic smokeless powder from scratch, etc. There is a project called Open Source Ecology which looks at all the machines you need for basic civilisation and lays out a roadmap for building all of them starting from just one machine, I think a similar approach for guns is the correct way to go and given the low cost of benchtop CNC mills (< $1500USD for a cheap Sieg X2 mini-mill and CNC conversion kit) I think its do-able.

First place you'll want to start looking is lathe turned casings. Expensive and time consuming but much more accessible than a homemade brass drawing rig I'd imagine. It's how a lot of rare brass gets custom produced in the US.
Projectiles can of course be cast easily and when it comes to powder/primer the chemistry is floating all over the internet.

>First place you'll want to start looking is lathe turned casings.
>much more accessible than a homemade brass drawing rig I'd imagine.
I did consider machined casings but there a few issues with them, the main one being that it still doesn't solve the primer issue. Even Luty used blank cartridges for the primers which breaks the rule of not needing anything potentially controlled, so realistically the person making the guns and ammo is going to need to do some drawing.
>Projectiles can of course be cast easily
Again though, the mold needs to be made. You can't expect someone in China to be able to order a 'Lee bullet mold #xyz' like you can.
>and when it comes to powder/primer the chemistry is floating all over the internet
Yes but the tooling to consistently make smokeless powder isn't. Mixing a bunch of chemicals together in a specific way doesn't magically make the extruded smokeless powder we can freely buy. Granule size has to be tightly controlled to ensure consistent burn rates and safe pressure levels.

You don't exactly need tooling to pull off making consistent grain sizes. There's a decent way to pull it off by experimenting with shrinkage after you put a wad of paper or piece of white cloth into sulfuric acid till it blackens then into a Nitride bath.
after that you can get something to grind it into your desired size.
Experiment with stuff like coffee, salt and pepper grinders.
Nitrocellulose is pretty stable, you can even put it into a blender to get finer particles if needed.

All you really need to rifle a short barrel (around 7 inches) is a hammer, a button and a stiff enough rod. Longer than that and you can do pull button rifling. It's pretty easy to come up with a contraption for that since it turns as fast as the rifling is being pulled through according to the twist rate you want (the main part is the sinebar which was also used for cut barrel rifling)

Furthermore, with long barrels you start running into problems drilling the hole in the first place, because you can't evacuate the chips from the hole as fast as you're cutting them.
The 'proper' way to do it is to use a gun drill, i.e., a drill that squirts coolant out through the end to flush out chips. But that requires special tooling, a special tool holder, and a dedicated coolant pump.
It's possible, but time consuming, to do it with a standard twist drill because you have to back it out all the way to remove chips.
What other options are there? Start with a predrilled tube? Some sort of electrochemical boring process?

>with long barrels you start running into problems drilling the hole in the first place
not if you have the right tools and a lathe.
You don't bore in one pass, you progressively drill for the 1st 6 inches, and for each extra inch you move afterward, you pull the bit out. You then flip the whole thing around amd drill from the other side, so you end up drilling as deep as 8-10 inches for a 16" barrel and 10-14 for a 20" barrel Vid also related.
Another way of doing it is forging a barrel from a flat, that is even more time consuming and you still need to straighten the bore by drilling afterward though you have less material to use. If your heat treatment is off you end up fucking up the entire process so it's much more difficult.
>gun drill
>special tools
lol no, you just need to change the tailstock out, that's it, the lathe does most of the turning, the gundrill doesn't turn, the material does.
>electrochemical boring
If you have weeks to spare, sure, just don't expect it to be a straight bore if you expect it to be left alone to do its own work. It's quite inconsistent if you don't know what you're doing.
Oh, the other way you can pull this off is using a Vertical Mill and raising the knee/lowering the head while pumping coolant into the bore as the material is moving toward the tool.

Truth on the primer issue. A boxer primed casing is easy to make since the primer pocket is drilled straight through, but if you could figure out how to make a berdan primed casing primers are easier to make since they're just a little copper cup.That could be stamped out of a hand press of some sort I'd imagine. You're right though primers are the most complicated piece of the cartridge. I'm not going to suggest we use any sort of flint or matchlock system. At that point sharp objects will probably be more effective. We all need to be thinking of how to get around the primer issue. Is there any solution to be found in electric ignition perhaps?
Molds can be made pretty easily if you've got a lathe/mill/drill press really any rotary metal boring tool. If you're in a country where for some reason those aren't available they can be made from a small engine. There are plans online. Lead can be harvested from car batteries and wheel weights.
I had in mind black powder which can be reduced to a consistent grain size by ball milling and subsequent sieving. A bit dangerous but so is this whole affair. You certainly aren't going to make high quality smokeless powder at home, but smokeless powder of a sort is doable if blackpowder simply won't do. Sheet nitrocellulose (flash paper) is easy to produce in the home environment and can be physically cut to smaller proportions and utilized. Effective? Hardly. Safe? No. Usable? Yes.

Redesigned the bolt, much cleaner now. The main assembly is coming together nicely. I've settled on .45-70 and I think it will be able to survive that given the very thick chamber wall that it has from the barrel and trunion. I'm a little concerned about the barrel thickness but the internal diameter of the stock tube is perfect at .459 and I can get other tubing with the same OD and smaller ID for a rifled barrel. I think that chamber pressure will have dropped enough by the time the rear rollers are no longer supported and start to move in.
As you can see, the guide rod, the bolt sleeve, and spring all protrude out of the front. I may extend the bottom square tube out under the barrel and use it for stabilizing the rod but that may not be needed. What are your thoughts?

>Yes but the tooling to consistently make smokeless powder isn't.
The tooling isn't the problem, but there is a problem of effort versus reward for home makers of guns.
Smokeless powders create much more pressure on the barrel than black/white powder or match heads, which means you cannot use simple pipes or other metal trash for a barrel and need to spent more effort into crafting a solid barrel that can withstand the pressure.
Then there is the fact that the chemicals needed for smokeless powder are much more volatile and regulated, which means you would have to go through the process of converting them from other chemicals that are freely available. So people would not only have to build their own workshop, but also their own laboratory.
In the end it would mean that these people would need so much space and spend so much money, that it is cheaper and less time consuming to jump through all the hurdle the state presents you with or buy a gun on the black market, just do reloading at home and make modifications to commercially available parts.
>>559221
>Is there any solution to be found in electric ignition perhaps?
Electric ignition is not a problem, but it would mean you either work with a cartridge where the power is exposed or a very short fuse. Both make the ammunition weak to humidity.
Alternatively you could use open little light bulbs as a primer, but you would have to create a special casing that can hold them.

The issue with additive manufacturing in general is that it won't be as strong as molds or CNC from a solid block. You're building material in layers with additive manufacturing, meaning there's much more room for failure, and you generally have to use weaker solids to form parts. It's great for disposable stuff like board clamps or robotic arms, but if you need it to last more than 300 slowly shit rounds from a gun, it won't help you much and the time/materials will quickly become more expensive than its counterparts.
Molten metal printing will solve this issue over the next few years, but molten metal extruding printers are expensive as shit and only good in a factory setting.

Ghost gunner is overpriced shit. Any CNC machine can do the job, and frankly unless you're producing firearms for all of your buddies or selling them, buying an 80% lower and the proper bits for a drill press is far cheaper since you can get a drill press on craigslist or from a thrift store occasionally for like $200.

No, the racial segregation broke down due to the adoption of Buddhism, previous to Sidharta the first Buddha the races were kept entirely separate, with the racially pure white brahmans at the top (this is what Sidharta was by the way), followed by the mulatto warrior and merchant castes, with the pureblood indigenous at the bottom. Buddhism was opposed to the caste system, and during the time that Buddhism was the majority religion in India the caste system broke down, and the purebloods mixed with the lower castes, and now no pureblooded Aryans remain in India, however the brahmin caste in India still retain roughly 20-30% white genetics on average, which is why they are far more pleasant to look at, and achieve at a much higher rate than the subhuman native purebloods.

I think roller delay is hard as fuck to pull off right. Consider flutting the chamber.
If you do build it, prepare a simple test too for the chamber (just a fixed fire pin attached to a block inside a guide-like structure with your chamber un one end and a stop on the other). It is very important to see how much the brass expands after the round is fired.

Roller locked, not roller delayed. There is no angled surface here and I'm not sure that it would be possible to make a roller delayed system with a second pair of rollers acting as safety lugs.
The front portion of the inner part of the bolt that drives the rollers apart protrudes through the bolt face slightly.
When the cartridge is fired it moves back a fraction of an inch but it should be enough to start the inner bolt moving back under momentum against spring tension.
The main bolt body is long enough that the inner bolt will have 2+ inches of travel before the rollers can move in and the bolt unlocks. And that's where the big problem is. I can shorten the back end of the main body, and I can eliminate the front rollers and probably still be fine, but this system long when open. It's also very heavy in the current iteration.
I've tried to trim material and weight where I can from the design but I think I may want to start a new model as a straight-pull and see how things go from there.

You don't need a CNC machine to finish an 80% lower. If you were doing it from the billet, that would be a different story, but you're not. You don't even need an actual mill, most people get away with a drill press and cross slide vice, hogging out the pocket with a drill and doing only the finishing pass with a small diameter endmill.

This is what I said earlier in the thread, the white sentiment against extermination rests on two pillars, christian slave morality, and gaslighting by the media/state, the first pillar is already entirely hollowed out and will collapse without the support of the second one, and the second pillar is built on the systems ability to absorb the consequences of non-whties living in our countries, and that ability is quickly eroding, the money which the state uses to subsidize the infrastructure of deception is procured through borrowing, it is only a matter of time until the market dependencies are normalized, and when that happens the entire machine of white disenfranchisement will collapse, the only thing that is necessary is for a white nationalist organization to have the infrastructure necessary to take advantage of such a situation. Trying to infiltrate and subvert the current power structure is retarded and will bear absolutely no fruit, the cultural marxists were able to infiltrate the state and subvert it because they were unopposed by the ruling power elite during their infiltration, we do not exist in the same paradigm, and we do not have the same path of action open to us.
Attempt to combat the current system through political action is stupid, since your'e playing with the enemy on their own playing field, according to their rules, the best you will accomplish is an endless cuckery of compromise and failure to affect real change.

Running away to space is not a realistic option for many reason, I will outline a few.
The only place to go is Mars.This is a highly undesirable place to live. It would be impossible to set up a human colony independent of Earth for for hundreds if not thousands of years. A life time in Mars low gravity would render you weak ass a mouse with weak bones as well. A person from Earth would be like superman compared to you and would rip you apart like a gorilla vs a person now.
Earth is the best place for us to be and running away from it is stupid and a fantasy that could never happen irl on any timescale that would save the white race.
p.s despite all the negatives I think it is very important for elon musk to be successful and start a human Mars colony,simply so we don't have all our eggs in one basket.But you can bet your left nut the Mars colonist will be chock full of "diversity" from the very first flight.

I don't understand your complaint, it isn't up to us to decide when the war starts, that is entirely dependent on the system collapsing, until that collapse there isn't a whole lot we can actually do. I'm not saying that because I like it, I'm just saying because it's true, lots of people have tried to fight against the system using their speech, and their right to assembly, all of them have failed, because the system aren't playing by the rulebook they hold us up to. They let communists, niggers, and spics get away with literal murder and rape, but as soon as they can spin a white man as being guilty of any crime, regardless of it being true, they do everything in their power to take him down and make an example of him. Quite simply, you can't go against the system on their terms and win, because they control the banks, and through the banks they own the media, and all corporations that we are dependent on for distributing alternative media, and most important of all they own the state monopoly on violence, put these things together and it's impossible to have an honest peaceful struggle with them, or wage an effective armed insurance against them. But, the thing that we have on our side is truth, and that is not to be underestimated, our worldview stands in concordance with fact, and theirs against it, this is the reason their system is beginning to come apart at the seems, and why it will inevitably collapse, the outfall of this will be the most nightmarish societal collapse in all of human history, all the various racial subgroups, and the ethnic derivations of the races are going to be waging a war all against each other, it won't be something that happens over night either, it is something that's going to begin fairly benignly, but over months or even years the small tribal conflicts will blossom out in to low intensity race war, and due to the state no longer having the banks to rely on propping them up they're going to lack the means necessary to maintain a sufficiently sized state apparatus to keep the developing racial conflicts under control, what's far more likely is that the various race conflicts start seeping in to the state apparatus, and it eventually seizes to function on any scale above the municipal.
And we white people will win for the very reason we've always won our wars against these subhumans, because we're better than them in every field, we're smarter than them, we're more trusting and less violent than them, allowing us to build strong social structures that are able far more efficiently support military and scientific endeavors, and our higher IQ means that we're generally far more successful than the non-whites.
I'm sorry to let you down, but you're not going to get your white revolution, we're not going to have a peaceful collapse like the Soviet Union, we're going to be in a concrete box locked in with all the subhumans, and the only way for us out of that box is by stacking their corpses.

If you're still here, the Workshop Practice Series is a good reference for basic stuff.
Also, I did a bit of reading, and the operations necessary to finish a 1911 80% lower are as follows:
>face ('deck') the top
>mill the slide rails
>drill and ream a couple of holes
>handfit the grip safety, if wanted
Of these, only the slide rail is particularly troublesome. You would probably need an actual mill for that.

>Yeah, I wouldn't use cans for anything that needs to withstand actual stress
Well the lowers are easy to deal with, the only things that really have stress on them, in a good design are the Barrel Extension/Trunion and Bolt (atleast in a rotating bolt design).
Roller Lock, Flapper lock, Rear Lock and Tilting Bolt depend on the upper receiver.
That can be fixed if you put steel inserts into the receiver itself with its own "skeleton" in the softer material by welding it together then "closing" the design by casting over it.
>>560060
It will work sure, but you need to do it in such a way that you don't have alot of holes in the casting so the structural integrity is uniform.

yes it would be far easier, but pointless in pratcise; a full auto can be as simple as the Sten or the M3 or the PPh… whatever, and all of these are only a receiver tube, a barrel, a trigger to catch the bolt, and a spring returned mass that's big enough to keep the case head from separating during firing. They're dead simple, with the only parts that are complete to make being the barrel and the magazine. But here's the impracticle part; a full auto burns through ammo almost instantly, which is why they are used only for cover / supressive fire, not for normal use.
>>557372
A milling machine is ideal, but they are costly, with the hobbyist chinese imports being $500 minimum. Many of guns shown, such as the Kolt 380, the table leg typewriter, etc. are all made from pre-form angle iron and sheet steel. A dremel/rotary tool and a cordless drill can assemble and/or build everything save for the barrel, which is where your lathe comes in. The lathe is the moher of all machine tools, and can double as a mill, if poorly so.
>>557404
for anyone, even experienced people, these take about 3 hours to make with no breaks or rests. It's boring, tedious and sometimes difficult to do without real machines likes lathes and mills. In reality one of these guns takes about 2 years to build, because it's a pick up and put down sort of hobby.

>>558763
just a thought; maybe forgo the carter pins and go with a trigger assmbly mounted inside of a bend segment of steel, with normal pins, being held in place by the sides of the receiver from the inside? In this way even overside holes or undersized pins wouldn't matter much because the reciever keeps them captive.

This is a bit different from most of this thread, but I'm floating the idea of making a birch stock for an A1 buffer tube because I have access to tons of wood and GI style fixed stocks are retardedly expensive for what they are. I would have to use small pieces of wood, maybe 3" max joined together by doweling and glue, maybe dovetailed as well for good measure, seeing as I don't have a really long forstner bit or big drill press that would be necessary to do it as a monolithic unit. I'm confident in my ability to join and shape wood to the right shape, but I'm concerned about how the stock would interface with the lower receiver, and how it would generally hold up to use. Would I need to fashion or use an end plate?
I also could easily obtain some beech, hickory, and maybe cherry, as well as oak and maple. At the moment birch would just be the easiest to process and I have more experience with it. Would I be better off using something else? Is this just a crapshoot to begin with? I'm thinking it might be a good idea to use a different profile, something more like what I show in the bottom of the image.

Rifle-length AR stocks have a round bit that sticks into the hole beneath the buffer tube.
Beyond that, the only thing keeping the stock attached to the buffer tube is a screw, so you'll need a buttplate that has a snug fit to the screwhole on the buffer tube.

If you can point me to a writeup on doing that in the home environment without great expense it sounds great. My main issue with making barrels is my lack of a lathe. Even the HF ones are several hundred dollars, and that would buy more barrels than I need. I could ghetto it up and chamber on a drill press, but that's probably just going to fuck things up and including a proper reamer would still cost more. I suppose I could ghetto it up even further and just straight ream it and ignore the tapering of 9x19. It'll fire.
I found some take-off subgun barrels in .45 ACP for $40 each I think I'll pick up a few of those instead. Already chamberd, crowned, rifled, and profiled so all I have to do is design a trunnion and throw it onto my design. Sitting on a small pile of Thompson mags so I don't have to get the Sten mags I was planning on. If I decide to start stockpiling submachineguns then I might invest in the lathe for low-scale cottage production work. Button rifling tools can be had on eBay for under $100, and I've got a 20 ton press to do it with. Chambering is really the issue.
Anyone made a homemade magazine? I've seen AK mags produced by tribals that weren't total shit. Pressing sheet steel over a mandrel and hitting it with the TIG would do it, wouldn't it? Hell could even braze it I bet.

I can't remember which gun it was, but something dug up on Forgotten Weapons used an even more simple delaying mechanism in that a fat, flat spring was screwed into the receiver in the path of the bolt's rearward travel to slow down the bolt just enough for it to not fly out the rear of the gun but not enough to prevent it from fully cycling.

Basically going full-retard to partially retard the bolt.

>Going to second lever-delayed.
>The rest require fairly precise machining and lots of spare parts.
Lever delay require precise lever geometry and bolt to bolt carrier mass relation. Even then there is less varience to allow with amunition in gunpowder and bullet weights. In rotational locking bolt you also have cartridges that are too weak to actuate bolt all the way, or so strong they shoot bolt in gunmans eye and break everything, but you have wide area. In noncomplete locking action with lever delay, you have lever geometry only for sertain area of ammo and it's smaller. Noncomplete locking gas delayed is self balancing because weaker ammo means weaker "locking" to act against weaker blow back, and the other way around for strong ammo.

Anyone have any ideas about making chamber reamers? I imagine they could be fabricated from drill rod blanks without too much trouble if one has the correct tooling. Would it be as simple as turning the correct diameters, tapers, shoulders, etc. and grinding flutes?
2d1c97 No.582936

I've never done it personally, but yes.
It'd be better to do it on an OD grinder, but you might get away with doing it on a lathe. Cut the flutes with a collet indexer and a ball end mill or slitting saw. Then heat treat and quench.
For short, straightwall cartridges you might get away with just using an adjustable reamer. Except that most straightwall cartridges are in fact very slightly tapered, so your mileage may vary.
My personal philosophy is that you make yourself what you can't just go out and buy. So unless you're wildcatting or you live in some hellhole where owning gunsmithing tools is verboten, you might be better off just buying or renting the tools you need.

If I were just starting out, I'd want a drill press and a lathe over a mill. Most of what you can do on a mill you can do on a lathe with a little bit of setup, and you can also turn things.
Then there's the normal assortment of hand tools, files, saws, drills, taps, mikes, calipers, surface plate, dial indicator, and so forth. Buy what you need as you need it rather than trying to buy everything at once.
If you're dead set on a mill though, you're probably going to end up with a used Bridgeport or similar. I'd stay away from anything made in a non white country, just on general principle.

It is certainly possible to machine a trunnion with the needed locking recesses and angles then set it into a stock metal tube. However, this would require a milling machine, or at the very least, a drill press. That is very helpful for most expedient firearms but it shouldn't be an absolute must.
The advantage of SMGs and pump or lever shotguns is that they can be manufactured with simpler tools and fewer steps.
Don't worry though, I'm working on a roller-delayed rifle that will have more of a safety margin than HKs are known for. I just want to make sure it can be made easily and with simple tools before I start writing the PDF.

Would it be feasible to make something like those drop-in crank triggers, but hooked up to a small electric motor and battery so that as long as a button "trigger" is held, it would be full auto?
I've seen pdfs of full auto conversions with homemade autosears and the like, but depending on the specific gun a lot of them appear to require modifications to some parts. It seems like something completely external (and therefore discreet, and quickly and easily removable) would be useful given the legal issue.
Come to think of it that would also allow you to set up a variable rate of fire or a burst mode much more easily than a mechanical method.

One huge problem with your idea, you need to time that motor to not out run the bolt. You can get more reliable results with a reciprocating charging handle, a length of string and a key ring.
>Loop around charging handle.
>Run line along side of receiver, then around the trigger.
>Put key ring on other end of line.
When you pull the key ring, the pressure is applied to the trigger. Gun fires, bolt cycles back, slack on the trigger allows it to reset, when the bolt slams home the line is pulled and the trigger is pulled once the bolt is where it needs to be.
ae2c25 No.590115

>One huge problem with your idea, you need to time that motor to not out run the bolt.
That was an issue I considered, and if I didn't know the hand-cranked version existed I would have dismissed the idea on those grounds.
What kinds of rates of fire could you expect to get with that kind of mechanism anyway? Is it low enough that outrunning the bolt a concern with the hand-cranked version too? Obviously it varies from gun to gun, but generally speaking.
20cdba No.590119

Not sure, haven't messed with them a lot, it is very easy to out run the bolt though. Its why most full auto or burst fire trigger packs have a disconector that hold the hammer/sear back until the bolt is forward. Its really uncommon to find a civilian trigger pack with a disconector though.
As for fire rate, it is very dependent on the firearm and to an extent the ammo.

>Its why most full auto or burst fire trigger packs have a disconector that hold the hammer/sear back until the bolt is forward. Its really uncommon to find a civilian trigger pack with a disconnecter though
Do guns not often have out-of-battery safeties that stop you from firing if the bolt isn't fully forward? I know that for normal "holding down the trigger" full auto you need an autosear to stop the hammer riding the bolt home, but if you're talking about simply pulling the trigger really fast, wouldn't an out-of-battery safety be enough?
Or does that kind of safety generally intervene after the hammer drops, or otherwise handle it in a way that wouldn't work for this?
I think I recall a Forgotten Weapons video a while ago where the ATF had taken issue with a safety mechanism for being too similar to an autosear, probably for this exact reason. Don't remember what gun it was though.
20cdba No.590126
>>590123
Most cases, the hammer rides the bolt as the bolt goes forward. Resulting in a light or no primer strike. Look up videos of people bumpfiring, they out run the bolt all the time and have to reset the trigger to get the gun going again.
The out of battery safety is typically the pressure on the hammer not being enough to strike the primer hard enough. A disconnector is a piece that will reset the trigger or trip the auto sear itself, when the bolt is in the proper position.
In my legal AK clone, I can drop the trigger with the bolt pulled back, you can do it with AR-15s, VZ-58s, ect. It will ride the bolt as it returns forward, at a much slower speed with much less power. Resulting in no bang. Your motor idea runs this risk without precise timing or a slow motor with multiple trigger contact surfaces.
And the gun you're thinking about is probably the civilian FS2000 that was brought in to the country, it is one of the few civilian rifles that has a disconnector.

What would happen if you chambered a round normally, then pulled the bolt just far enough back to unlock and pulled the trigger? Or if some obstruction prevented it from quite closing. The hammer would have almost its full normal fall, so wouldn't it still be able to detonate the primer despite the unlocked breech?
This is starting to veer away from the thread topic though.

a7408c No.593878

Well on a revolver the rim of the cartridge is typically what holds it in place inside the cylinder. A bolt wouldn't be able to strip the round into the chamber if it's physically stopped by the cylinder walls. You wouldn't be able to use a traditional bolt for this reason either, as the cartridge rim needs to contact the chamber for proper seal. You could mitigate this with a rimless cartridge, though you'd need a Medusa M47 type mechanism to retain the cartridges. It'd be easier to abandon the traditional cylinder design and go for something akin to the Metro 2033 Shambler.

Possibly, but what you described wouldn't really be practical.
The problem with revolver rifles and shotguns is the gap between the cylinder and the throat of the barrel. Gas escapes through that causing both a loss of performance for the ammunition and severe burns to any limbs nearby. Seriously, even the top strap of a revolver can be cut by the high pressure, high heat flames blowing out of that gap.
What you could do is have the cylinder mounted on the front of a reciprocating pin that moves slightly backward when indexing, then moves forward and locks in place when firing. Think of it as a kind of lever action/revolver hybrid that closes and seals the cylinder gap.
I'm not aware of any examples of such a system, and there isn't any practical upshot to this now, but it could have been a serious improvement in the mid 19th century.

You could also bore the end of the cylinder bigger and have the barrel slide into it. Of course it has to move in-and-out as it indexes the next round, and I'm not sure how all that extra weight would affect the trigger pull. Especially if you go big and make a revolver rifle.
>>594027
His ignorance is indeed unforgivable, but I've gathered some information on this exact subject: apparently the Nagant can fire 7.62 revolver cartridges other than its own, but the gas seal doesn't work with them. And it works just like what our American friends described, it even has a nipple at the beginning of the barrel and a matching hole at the end of the chamber. Yet that's not enough without the rather special ammo.

Actually, how would a proper and complete gas seal affect the whole bag of problems that is firing completely different cartridges from the same revolver? Let's say you have a .357 Magnum revolver with this moving barrel system. Would firing .38 Special from the same cylinder have any negatives compared to a dedicated .38 revolver? Or what about putting a 9mm Parabellum cylinder into it? I guess firing 9mm from the .357 cylinder wouldn't be any different from firing .38, expect for the blown-out cases.
9bee2d No.596210
>>594027
>>595454
I didn't forget about the Nagant. I didn't mention it because it relies on the trigger finger to lock the cylinder forward. Not really the best method for a secure lockup.
What I was describing was a revolver where the cylinder is moved forward by a pin or bolt and locked in place during firing as opposed to being pushed forward by the trigger but remaining unlocked. Without a firm seal the vented gasses may cause serious injury. This is why revolver rifles and shotguns never really caught on.
I have looked for something like what I described, a lever/revolver hybrid and the only production guns I found were SAO revolvers with levers to index the cylinder so they could be sold in countries with harsh no funs laws.
>>595568
Let's say you have a .357 Magnum revolver with this moving barrel system. Would firing .38 Special from the same cylinder have any negatives compared to a dedicated .38 revolver?
The .357 mag is just a .38 special with a hotter load and a slightly longer case. You can safely fire a .38 special from a .357 mag revolver but not the other way around. The .38 special will have less recoil and poorer performance but otherwise there will be no negative effects. If you have a .357 mag revolver it's probably a good idea to practice with .38 special ammunition.
>Or what about putting a 9mm Parabellum cylinder into it? I guess firing 9mm from the .357 cylinder wouldn't be any different from firing .38, expect for the blown-out cases.
While a 9mm Luger will fit into a .357 cylinder, it will need a retaining clip to properly seat. Because it is much shorter it will have more free bore before engaging the rifling in the barrel, causing much worse accuracy (keyholing) and damaging the throat and barrel over time. The brass will blow out and it will not be safe to reload even if pressed back into shape.
Use the ammunition your weapon is designed to use, don't just jam any old crusty found rounds into the chamber.

With a halfway decent drillpress, let alone a proper mill, this design seems fairly easy to replicate and good for at least pistol calibers.
I'd say having the bolt lock into an open slot at the top of the receiver may help prevent at least some accuracy issues typical of the action and relocating the oprod to the bottom, like the M1 Carbine, for aesthetic reasons would be neat.

when retarding piston become fouled, it is more frequent to become stuck in up position not down, so you don't have non-delayed action cycle that shoots the bolt in your shoulder and destroys the gun. You instead have a jam and no cycle after shot.
Also I have doubts. Pressure can be so high that piston scrape off the foul back into the barrel every cycle. Maybe self-cleaning like vietnam ar15 lol but if it is, bolt and piston probably wear out quick from rubbing with high pressure.

Depends. There's a few people who sell jigs for drill presses to mill out 80% receivers that can be done by anyone who can follow instructions. The guy who made the 3d printed gun now sells a CNC machine that machines 80% receivers for AR10s, AR15s, and 1911s. It's apparently user friendly enough that anyone, even soyboys who don't know their way around tools, can do it. I wouldn't be surprised if he or someone else created a CNC machine and associated jigs to mill out most parts for a functional rifle.
As far as doing most of it from scratch, that'd be difficult unless you have a decent amount of metalworking experience and have solid knowledge of firearms. Machining metal parts with fairly tight tolerances is a pretty difficult skill.
5d5005 No.609478
>>557404
Anyone with a hacksaw, a set of files, a drill, and patience can make a functional expedient firearm as in the PDF. With proper machine tools much nicer pieces could be cranked out no problem. The problem for the average joe is the acquisition of that tooling. A used bridgeport can be had for around 1000 USD, depending on the condition, but it's 8' tall and weighs 1.5 tons. Similar for a proper lathe. All the necessary tooling would be another 500 on the low end, if you have the patience to track down deals, and retrofitting a digital readout and ball screws to enable someone with no training or common sense to operate would add a hefty bit more.
Welding isn't hard. Welding nicely takes years. with MIG it's really easy, but there's a big startup cost. TIG takes more skill, but is going to be a lot more flexible as far as applications go. Also expensive. Stick is the cheapest, but the results aren't pretty, and getting functional welds takes practice. For the guy in his garage, pins and screws are the way to go.
>>609165
Milling on a drill press is a barely functional technique. For an AR lower, with a jig, precision isn't as much of an issue, but you will not be able to meet tolerance for anything requiring a degree of precision. More importantly, the Jacobs and Morse tapers found on most drill presses do not respond well to loads on the X and Y axes. Unless very light cuts are made with very rigid work holding, the chuck will slip off the taper. A wood router is designed to takes loading perpendicular to the spindle, and with a endmill in the collet would probably perform better than a drill press.

That's where you have to take bolt travel into account so that the hammer or striker is properly caught before the bolt goes into battery.

Good, you aren't a complete retard then. Theoretically you COULD make a barrel out of aluminum, but it would have to be a lot thick than a standard barrel and would be probe to, y'know, melting. I would regulate aluminum to gunparts that aren't in contact with much heat, and don't move around or scrape against other parts too much. Meaning it's basically only useful as a stock, and possibly a magazine, but there are other materiel that would be more suited for those roles anyway so unless there's something glaring obvious that I've missed, there probably is aluminum is basically useless in gun manufacturing.
79889d No.609570
Do you live in a NOFUNS shithole? Do you have access to rudimentary tools? Do you have no access to ammunition?
Fear not: The army gives out free ammo to citizens. Yes, you heard right. Free ammo for every citizen, as much as you can find. All you need is a basket and some knowledge in differentiating the different kinds of ammunition you can find innawoods.
First of all: Ammo doesn't grow on trees. It grows in the ground. Some places have a lot of it, while others have none. You can be sure that there is at least one spot in your area. Check on openstreetmap.org for any "Red" areas. Those are military training grounds most of the time. Depending on what area you live in, the government may have fenced them off to protect the ammunition in it's larval stage from getting destroyed by hikers or deer.
After you have located a good spot near you, all you need to do is prepare your gear. Get a nice basket that can hold a medium amount of ammunition. Put some regional mushrooms on top. They will not only absorb the moisture on the ammo, but also protect the (easily startled) ammunition from envious onlookers.
Now head out towards the area. Make sure to park your vehicle a way away, to avoid crushing the prescious larval ammunition while it is still in the ground below the road. Get out and start walking across fields (ammunition tends to grow along paths and roads, avoid walking there). Once you are "in the red zone", be careful not to make too much noise. Not only can you scare the ammo away, but it could attract unwanted attention. Often times the government doesn't want unlicensed ammo-picking, because they are afraid that you might damage the local eco-system, or harm yourself by erroneously picking a dud.
Walk through the forest in appropriate high-vis clothing, to avoid getting into a training accident and to blend in with the natural population of land-keepers and foresters. Going on a weekend will make any encounters less likely, because of the natural biorhythm of the modern ninetofive military. Once you are sufficiently far into the red zone you should turn back towards the pathways. Look into ditches and holes at the side of the roads.
Here you may find the precious ammo in it's pupa-state: the world famous "blank dumps".
The formation of these natural phenomena is simple, but one of nature's most cruel sights. Soldiers out training often carry blank ammo to avoid accidents and allow them to simulate battle more realistically. After such an exercise they are often left with blank ammo. Most of the time, the superiors set up one last ethical "simulation" where the soldiers are instructed to shoot every last blank they still have, other times the superiors have, due to a lack of sufficient planning, run out of time for such a slow and graceful death of the ammo.
To avoid having to turn in the leftover blanks, and save time, they instruct their soldiers to dump the ammo in a ditch close to the road, and hurry on back to base. These blank-dumps, while a cruel treatment for any soldier, are a miracle for any ammo-collector. Pick as many pupa-state rounds as you can find, and put it into your basket. Don't forget to snugly cover everything with mushrooms.
After you have picked your fill, head back to your vehicle and leave.
Once home, you can aid the blank in it's transformation by plying open the front of the case, pouring out the powder, grinding down the front of the case, pour the powder back in, and seat a new bullet into the case.
There are some risks associated with the picking of pupa-state ammunition on government grounds, but they are well worth it.
Picking fresh ammunition from the fields is the most healthy way to kill your foes.
I hope you enjoyed this little excursion into nature. Have a safe day and praise the military for wasting money.

Nah, it's simple, it just takes is a lot of practical work to get right, and some theoretical knowledge.
All you need to do is buy a whole lot of metal scrap. Any sufficiently think metal will do. Clean it, file away the rust, and then just go ham drilling/milling/turning at it until you get the feeling for it. You can buy it by the ton, have it sit in your backyard under a tarpuline cover, take a heavy block inside, saw it into smaller parts and just build random shit out of them. Like cups, pens, fancy paperweights, drill a smiley face into them, hammer-heads, and even
Get a lot of the same tools. You will break them, or wear them out sooner or later anyways.
Obtain a cutting-machine-operator's hanbook (or whatever the proper English term for "Tabellenbuch der Zerspanungsmechanik" is). They are reasonably cheap and list the revolutions per minute that are best for most common steel/tool combinations to not ruin your tools within an hour. Pirate it, print necessary pages, stick formulas to machine, keep pen and paper in your pocket
Also: any discoloration of the metal due to heat is bad unless you want to heat-treat the part afterwards. Avoid it. If the metal is getting a hint of any colour, either add more coolant or reduce speed. What is happening is that you are heating the metal to a point where either the surface is so hot that it reacts with the oxygen of the air, or you are heating it to a point where the internal grid flips. Both are bad for your parts and the heat is not worth killing your tools over.
For the love of god: don't wear gloves, do wear eye-pro and don't wear long sleeved shirts around the machine. Always fucking ALWAYS secure your part properly. No matter how low the revolutions per minute. Fucking do it. I almost decapitated a fellow worker with a bolt shooting through the hall at SANIC speeds because I was too lazy to clamp it down properly.

It seems to me, that increasingly it's easier to simply machine a trunnion compatible with the barrel and bolt of your choice, and use extruded aluminium to build an upper by simply bolting that trunnion in. Plenty of companies will build custom extrusions for you. If it's a large enough buy, you could certainly justify the expense, and nobody would really know what these extrusions are for. So with that in mind, I'm leaning toward getting on my work PC and designing something that could reasonably be built at home. A sort of FOSR(Free and Open Source Rifle). I've also thought about stamped sheet metal, but the problem is most of the time you start with pre-cut blanks. The ideal would be to be able to make it all yourself while only buying a few critical parts.
