Wew, my favourite thread didn't survive these turbulent days. But it's an image board, in a way or other it was destined to disappear. This time we shouldn't even limit the thread to just weapon designs, throw in everything you've got.
To start it off, in the vein of giving belt-feds to everyone here is this extremely autistic idea: ammo belt bandoliers. Basically instead of an ammo box you have a belt with ~200 cartridges in a bandolier you swing over your shoulder, and the weapon feeds from it. Of course it shouldn't be just a piece of canvas, but something that actually protects the belt, has some rollers in it to allow seamless feeding, is padded to make it more comfortable, etc, etc. Then it just needs a feed chute placed about next to the hip. I think it would actually work better with bullpups.
Now, officially an average infantryman in the US Army carries 210 rounds in 7 mags and have an ammo box with a 200 round belt for the SAW gunner. Instead with this system a right handed soldier would carry a bandolier over his left shoulder to feed his weapon, and an other one over his right shoulder to toss it to the SAW gunner if he is running low. Of course the SAW gunner should carry his own 800 rounds in one of those fancy ammo bags.
Bonus: some Czechnology, the URZ family of weapons. From basic service rifle to GPMG everything is here, and all of them are belt-fed. It was chambered for 7.62 NATO, because they made them for export. The feed system is quite interesting, they managed to combine magazines with belts. Take a look at the patent: http://www.google.com/patents/US3507186

At a time I was very interested in some alternative reality where air rifles and spring-powered crossbows became much better than muzzle loaders during the industrial revolution, and so instead of smokeless powder people concentrated on those weapons. And also steam power became a lot more widespread, so every nearly every household had at least a small one, and vehicles were powered by steam instead of internal combustion. So, yeah, basically steampunk without the baggage all the retarded shit that makes steampunk so horrible. But for such a world to work you'd need every second man to be a skilled machinist, and not even the most autistic Asian population could make that work.
Still, look at this for inspiration:

Anyway, what I really want to say is that you can make air rifles a bit more potent by coating the projectiles in a combustible oil. There are actually commercially available oils out there. Combine that with your idea, and you could make something surprisingly effective, at least by the standards of the Napoleonic wars. Imagine some mad inventor moving down whole rows of infantry at the beginning of the 19th century with one such weapon.

Combine the ubiquity of having a couple bar of dry steam on tap with the utility of having a hit-and-miss engine for running water pumps, farm equipment, electric generators, household appliances, any sort of wood or metal working power tools, medical devices for treating 'hysteria' in women, and god knows what else?

>and vehicles were powered by steam instead of internal combustion
So basically the UK up through the 30's and 40's? Steam cars were preferred to internal combustion due to ease of use, lighting a gas burner being a lot easier than crank starting a gas engine, and steam trucks or tractors were often the only way to do any heavy hauling.

IIRC the gas seal was much of what caused the horrible trigger because you have to move the whole cylinder back/forward against a seal with each trigger pull.

Exactly. But imagine if it happened right at the start of the industrial revolution, and instead of massive urbanization you'd first have every blacksmith at the end of a village replaced by a machinists who wants to make crazy new inventions, and then technology progresses along the lines of "if you can't build it in a shed with 2-3 good friends, then it's either a miraculous machine too complicated for the average person, or shit, completely shit". I mean, even the bongs didn't build their Enfields in small workshops all over the country.
>So basically the UK up through the 30's and 40's?
Kind of, but again, more ubiquitous. As far as I know the average person didn't have a car well until the 50s and 60s, and unfortunately those weren't steam powered.
>So basically the UK up through the 40's and 50's, where an engine lathe and drill press were considered essential equipment for any garage workshop?
Indeed, but a workshop powered by its own steam boiler wasn't considered essential for a house, right?
Basically what I wanted to avoid is that terrible thing called steampunk. Usually it's either the modern world with in 19th century clothing, or the 19th century with modern or even sci-fi technology. Both of them are terrible when the world building is supposedly around specific forms of technology. So in a way it too would be science-fiction, just instead of a possible future it would focus on an alternative past.

That's simple, just turn it into an autorevolver by copying the Jackhammer's blow forward action. The layout should follow the Mars revolver, so it would be a "bullpup". I've been even thinking about the design and the possible ways of manufacturing the individual parts. The only problem is that I'm not sure if firing all these wildly different cartridges is mechanically safe and sound, even with an adjustable gas port.

Got an idea for a pistol firing cased telescopic ammo after thinking about the Pancor Jackhammer's action a bit:
>barrel is fixed in place, there is a gas seal where the slide ends
>there are two gas ports cut into the barrel behind the gas seal
>there is a second gas seal behind the ports, this one is fixed to the slide
>when the gun is fired the slide (that is pretty much an annular gas piston now) slides back, revealing the gas ports and letting the gases out
>bolt is also fixed in place, the slide only actuates the moving chamber
For simplicity's sake the barrel's gas seal should be fixed to a muzzle device instead of the barrel. This way you'd just have to remove the muzzle device and move the slide forward to get it off the gun. And instead of threads the muzzle device should be affixed via a bayonet mount.
Now, I don't have an idea for the chamber, but our resident Finn already came up with this action. I don't really understand the geometry, so I'd rather not try to explain it. He said it's similar to the Kriss Vektor's bolt, but with the magazine laying parallel to the barrel.

Ah. I do remember this one. I was suppose to get in detail with the action but I never did.
This is a composite pistol ("Lynx pistol") which uses CTA-style ammunition which seals the chamber's front to the barrel by expanding. As the exact opposite to my usual designs this was a vision of the ambidextrious future police service pistol with functions like removable and pistol specific trigger("trigger key") which also acts as a fire control. So it's a "robocop" pistol of sorts. With my lack of time and inspiration inducing spinach I doubt I'll return to finish it. But if it's of any interest then I'll go a bit in detail with the action and hopefully that will give you a better insight on it's geometry:
The barrel is fixed onto the frame and it's shaped in such way that the chamber slips over it.
The firearm basic mechanism consists of the following parts:
-sheet metal frame encased in plastic housing
-chamber
-bolt
This excludes small parts and magazine, so until explored we'll just assume they work by magic.
The chamber itself isn't attached to the barrel, so you must think the barrel as a blank of sorts. The chamber is attached to the bolt by a link. Both the bolt and the floating chamber run on rails cut into the frame. We're going to assume that the gun isn't loaded. To load the pistol you'd do what's commonly called "fanning". So to load the gun you would position your hand as if you were going to rapid fire a single action revolver. You sweep the side of your palm over the top while pushing down. When your hand is over the bolt it should push down and by doing so load the chamber.
When fired the gasses in the chamber and barrel expand, and cause the bolt travel back slightly. This expands the previously tight seal between the barrel, chamber, and cartridge hence allowing gasses to fill this newly formed gap. The theory was that this would allow gasses to have more surface which to push and help initiate the reloading action (which it doesn't happen). When the bolt finally starts traveling downwards the gasses have vented and the pressure in the chamber is low to normal, thus preventing the CTA cartridge from traveling backwards when the bolt moves and exposes back of the chamber for reloading. The bolt continues to travel into the grip while pulling the chamber with it. Since the bolt runs on rails it is forced to tilt and land over a new cartridge. In doing so the new cartridge pushes out the spent cartridge and any debri. Because of this function the spent cartridges are tossed in the firing direction. Eventually the recoil forces are spent and the spring pushes the bolt back upwards, hence forcing a cartridge to come off the magazine and be pushed deeper into the chamber by the bolt's upward movement. The chamber and bolt return to their original positions and the firearm can be fired again.

Now, this is the one part I don't understand. The only think I can imagine is that there is also a rammer in the grip and that rams up the new cartridge into the chamber.
>>482221
>I'm unaware of anything about the magazine design that'd render it inherently incompatible with longer casings
The cartridges have to be straight walled, so you'd have to design them for the weapon. Although CTA cartridges are straight walled, but then their actions tend to be rather funky, so at that point the only thing you keep from the P90 is the magazine's design and placement.

But yes you're right. It's either that or a device which alters the upwards movement and tilting angle.

I think you could use this action for a floating chamber gun that fires telescopic ammo. Here is one of my beautiful drawings to demonstrate what I thought up. So it has a fixed bolt and the chamber moves in two rails. There are springs inside the rails that apply a constant downward pressure. The op rod is "hollow", so that the chamber can go down under it. Then the gas piston's rod also acts as a rammer and loads the cartridge, then its spring moves it back to position. Of course it goes through a hole in the end of the op rod, and gets thinner at that part, so it can still push the op rod. The upper receiver only has the barrel and the bolt, everything else is fixed to the lower (including the rails the chamber rides in).

Gatling SMG functioning much like a Dardick would except it's entirely electrically driven and both chamber and barrel share the driveshaft.
And a helical magazine because fuck you, I'm on a roll.

Fuck, I like it. I take the motor also drives the helical magazine, right? And if it's electric, then might as well go all the way and make it a bullpup. And make the ammo electrically primed too.

Well, yeah, the ammo is supposed to be electrically primed.
No need to power the magazine though, that there is just going too complex for your own good.

I've got an idea:
>40mm AGL like the Balkan
>but it's a floating chamber design
>projectiles are rather long and finned
>they have an internal piston, just like the Fly-K mortar
>because of the floating chamber design the loading mechanism can slide the shells onto the spigot
Basically it would be a fully automatic silent spigot mortar-gun that can't even overheat.

And as I posted this I've just realized that you'd have to somehow harness the recoil to cycle the gun, as all the gasses are trapped inside the gun. Still, there are plenty of recoil-operated designs, so it's hardly impossible.

Out of interest are those there as just a 'Hey guys, look what I put on my gun!' thing? Or are you supposed to grab the balls and use them as a forwards grip? Because that last one does not sound like fun.

With the possibility of the Hearing Protection Act being passed, I've been thinking of how to best take advantage of the new market opportunities the deregulation of suppressed weapons will present.
As with any market opportunity, one must ask themselves what the largest problem out there without an adequate solution, that is the key to initial success (IMO). So what is the biggest problem with suppressed weapons as they exist today? In my opinion it is the fundamental compromise of needing power from a subsonic round. After all, what's the point of having a suppressor if the crack of a supersonic bullet negates your efforts at sound reduction?
So what is the answer? There's only one commercial subsonic round on the market today that's common enough to be considered cheap, the venerable .45 ACP. Of course, .45 isn't powerful enough for a carbine or rifle and even the largest subsonic niche/wildcat cartridges (.300 Memout, .458 SOCOM) are still less powerful than the lamest supersonic pistol sized carbine rounds in terms of energy. Thus, there's a niche for a 2,500+ joule, subsonic cartridge in the suppressed market.
So how do you get that much energy from such a sloe bullet? Duh, mass. Enter the 800 grain .50 BMG bullet. Tale this and place it in an available, SAAMI accepted case from a large manufacturer and you've got yourself a stew going. My choice after just a few hours of research would be a Winchester Short Magnum case, special ordered without a neck. Since one only needs ~70-75 grains of powder to propel an 800gr .50 BMG bullet to the 1,100ft/s barrier, there is more than enough internal volume to accommodate the bullet and powder load even with a necked down case while still staying within the overall length of a 30-06 length action design. You'd have rifl$-class power with a truly quiet report.
What does /k/ think?

Sounds like something that needs some research.
>Optimal barrel length to keep velocity lower than super sonic.
>If exagerated porting of the barrel (similar to the VSS/VAL) is needed to keep velocity down.
>If faster burning powder would be beneficial (similar to .300 blackout).
Are you going for bolt or semi because I think a 700grain .50bmg projectile will lead to some length issues?

I had no idea that existed. While I feel a little stupid for not knowing this already existed, I also feel vindicated by the fact that my concept is so fundamentally sound that someone is making almost the exact same thing on a commercial scale.

I wonder, would replacing mortars with rockets work? Imagine the same kind of shells, just with a simple rocket motor in the tails. That way you could launch them from a lightweight spigot-mortar like device, therefore you wouldn't need a barrel. The downside is that you couldn't vary the amount of charges, so you'd be forced to "go full power" with every shot.

Artist was just autistic and couldn't draw a fluted barrel to save his life.Lack of a grip, though, that's due to poor choice in reference.

How about a bullpup GPMG with a tripod similar to a Lafette mount? If the tripod has a periscopic sight and a trigger, then the only difference for the gunner and his assistant is that the belt is closer to them.

It could also be the transition between trench warfare and a more mobile, fluid form of war, at least coming from the great powers. Less powerful forces with no air support still have to engage in some form of trench warfare, so I guess they could still have a place, but I'm not so sure.

I don't think that a modern wheeled mount would weight that much more compared to a modern tripod. Especially if you don't add a shield.
>>516716
But why would you switch from wheels to legs if warfare is more mobile?
e30f0a No.516911

Only if you were a poorfag with poor logistics and mobility. Some Novorossians put a KPVT on a wheeled mount.
63f5f3 No.517028

Do you mean that the infantry doesn't need wheels to move around a machine gun that usually weights more than 30kg with the mount, because they can put it on a car? Because the wheels aren't for marching in this case, but to quickly reposition the machine gun during a firefight. You could put an ammo can with 1000+ rounds on the wheeled mount and two people could still just grab it and run to a new position.

Legs are lighter, more maneuverable and if you can do without a bipod you generally will go out of your way to remove that thing.

Could a modern Bren gun be of much use? I don't mean in terms of the action, but as in an LMG with a top feeding mag that can be quickly swapped between bursts by the assistant. Eh?
