They make frames for those? I thought it was only 9 and 40 compatible frames?

>>684856

I own 5 80% lower AR-15 lowers. I haven't touched them yet and I have no AR-15 parts whatsoever. The only funs I own are a 10/22 and a Glock 17 my dad bought me when I turned 21. Can someone recommend a upper receiver that is good when I do finally build one of my five lowers? The lowers I own were purchased when they were on sale. Thanks

Will make the best mm glock as well as .45

>>684873

Aero Precision is what I went with for mine

So where do you get your parts kits? Ever since these got put out, people have been buying them up or jacking up the price while pulling parts from police trade-ins that normally don't sell.

>>684873

Honestly any milspec upper is fine unless you're looking for something specific (no brass deflector or no forward assist). Brownells is having a special deal for stripped uppers, which is what I imagine you're asking for.

Put one of the Polymer80 glocks together and I've found that putting in a Gen4 extractor is necessary for reliable function. Little fucker wouldn't stop failing to feed and extract.

>Not having a from 0% manufacturing hobby shop in your own house

>>684911

midway USA, rockeybrass, the polymer80 website itself

>>684918

it's fun and helps you get into gunsmithing with a little hand holding plus you get something unique that you built exactly how you want it to be & look

>>684931

yup! not everyone has a lathe, mill, 1,000 hours TIG/MIG welding, etc etc etc

I just want to do something with a dremel or a drill and some files/sandpaper

Are polykits worth it for the AR? Are they that bad compared to metal kits? Thanks

>>684955

Do you want your shit to break? No stick to the standard aluminum or alternatively weld a stamped steel one.

>>684930

Yeah, jammed that shit in for sure. The casings weren't getting pulled into the chamber by the extractor's hook. Bought some snap caps and everything chambers just fine.

>>684856

If only we could have those in Europe.

you burgers need to open a black market to sell those to your eurofag brothers

>>684921

>”building”

bitch you are assembling. This shit is legos.

>>684997

How many do you want and what's your address?

>>685013

Hey.

I would need about 20 of them.

My address is

Eisenhowerlaan 73, 2517 KK Den Haag, Netherlands

Let me know your prices.

Thank you very much.

>>685011

Semantics, fine, I'm by law manufacturing a firearm.

>>684963

they got polymer ARs pretty much figured out so they don't break, they're reinforced with metal at the "weak" spots these days.

>>684955

go try one, they're easier to drill through and ok to fuck up for your first build

>>684997

are you muslim? I'm sure the CIAniggers will be happy to arm you

>>685035

Dutch cabbies sell em by the 11's and give the 12th for free.

>>685035

No, I'm just a regular white guy, the CIAniggers will not want to arm me :(

>>685062

You are more than welcome here, my friend.

slow fucking board, eh? My G19 build came in.

>>685788

Is it finished?

someone 'splain WTF the 80% parts are VS the 20%, and how that figured.

>>686028

>80% parts are VS the 20%

Marketing gimmick.

>>686028

An 80% reciever is by law not a firearm so it doesn't need to go through an ffl or a gun store. This means though that you have to put some work into finishing it.

>>686896

>that everything the ATF does must be 100% pants on head retarded.

This is probably a bigger reason that marketing gimmick. It's still a marketing gimmick term.

I hope you’re not planning to use one of these frankeglawks for EDC.

>>686909

>I hope you’re not planning to use one of these frankeglawks for EDC.

I do it all the time, what about it bitch?

>>686913

I was addressing those of us who aren’t legally prohibited from purchasing firearms. For you it’s a good option Paco.

>>686926

Why?

>>686926

>I was addressing those of us who aren’t legally prohibited from purchasing firearms.

No you didn't, cocksucker. Though I would HIGHLY recommend not building a firearm if you are legally prohibited from purchasing a firearm. Just carry a black powder pistol as your EDC, it's not a firearm.

>>686931

>hooktube

>>686931

Thanks for the YouTube legal advice Diego. However it’s incorrect to say BP is not a firearm. Federally yes, but states set their own laws, most of which still prohibit a felon from carrying BP.

>>686934

>but states set their own laws, most of which still prohibit a felon from carrying BP.

Yes you are correct, you would need to consult a local attorney.

Finished an 80% build. Slide's smooth and she'll eject rounds just fine.

However.

When I pop a magazine in and let the slide forward, the round won't go in. It'll catch on the lip of the brass to the top of the chamber.

Thoughts? Just get a new (nicer) barrel?

>>687242

An 80% what? AR? Glawk fody?

>>685792

yes! I need to do some finishing touches but I put it together and it functions.

The striker was really hard to do with depressing a spring while putting those tiny plastic cups on. Glocks are interesting in what went into making them work.

>>685796

I will post pics, I followed this relaxing fellow's videos for most of my build: https://www.youtube.com/watch?v=L7RSN22BlCc

>>686028

80% is what the ATF determined the maximum a firearm can be completed (their definition of a firearm which is the frame/receiver) before it needs to go to an FFL.

Check out their determination letter. 80% builds have been ok for years and aren't going anywhere unless some (((Las Vegas))) tier bullshit happens.

>>686857

This. And the work as to be machining, they can't just mail you a bag of parts that click together, you have to remove material with a tool.

>>687242

check my video above and see if that helps?

>>687260

glock 19.

>>687264

>The striker was really hard to do with depressing a spring while putting those tiny plastic cups on.

So assembled the slide as well? I just bought a vickers g19 slide for a pretty good price considering it was during the whole p80 compact craze that was going on.

If any of you niggers still have a (((faceberg))) you could visit the "80% builder" page. The dudes there are pretty knowledgeable on the subject and have posted numerous build guides and walkthroughs, as well as jig, endmill, and router pros/cons and routine issues/occurrences.

I threw together both a 9mm PF940 and a way overdone AR. Those took up just about all my disposable income for a little while. Glock parts are insanely expensive; even though it would have cost around half of what I spent on the build to just buy one, It's worth it to keep it off the record.

>>687456

>paid double for non-sellable frankenglawk to keep it off the record

Do you not know what armslist is?

>>687470

Not on my state

>>684856

Currently: AR15 (a super shorty .300BLK pistol, and a recce inspired 5.56), AR10 (20" planned), a 10/22, AR9 (glock mag), G17 (original P80, might just practice and learn how to stipple on it because it's ugly), G19 (chopped into a 26 grip, I plan on carrying it one of these years),and a P228… and I think that's it right now.

Ordered: Nothing so far.

Issues: Money.

Wants to build: M535 to MG3 conversion, 22/45, more glawks, ARs so I can share with loved ones. Kind of want a G43 even though I chopped the 19 already. I think I'll buy it when it comes out because why not.

If AK builds were still a thing in 5.45 I'd have bought a Tantal.

Realistically, how much do I need to drop to start building lower 80%s for AR 15s? I have a drill press and a garage and I'm pretty handy with tools. I've also got 1000$ saved up towards a gun but don't want to just go out and buy one.

Should I stone P80 rails or is it best to let it break itself in?

>>688311

Milling with a drill press is pretty awful. I completely fucked up the spindle taper on mine. It can be done, but if you don't have a mill, the best option is a router jig. That's about 150, plus a compatible router. For the rest of the construction you will want to have a set of roll pin punches, a barrel nut wrench, vise blocks, and hex keys. You can get a complete upper for less than $200 now, and an LPK will run somewhere around $30.

I'm building my first ar-15. I decided to go with a 5D tactical jig and Aero parts except for the Toolcraft BCG, Faxon barrel and gas system, Noreen 7075 forged lower, and B5 Bravo stock. I've finished the lower and both the upper and lower parts kits are assembled. Im just waiting on the barrel, handguard, and gas system to get here now. Everything function checks except for the bolt catch. Sometimes it catches, sometimes it doesn't. When it does, a hard slap to the reciever usually makes it release. I'm going to compare it to a friend's ar and the Deterrence Dispenced CAD model to try to figure out if it's the catch or the lower reciever. I've tried to manually use the catch and got the same result, so my mags are fine. I can tell that even when I put my fingers in the mag well and force the catch up, it's barely touching the bolt lugs. I'm really hoping the reciver wasn't machined incorrectly. Aside from that though, the build is going great!

>>688575

Appreciate it. I just dont get it man. All the parts are supposedly mil-spec. I know that isn't 100% true; coatings aren't identical and other little changes are made. But the dimensions should be the same. I even measured the critical ones and compared them to dimensional drawings of the ar-15 and they seem close enough. I'm considering ordering another mil spec catch from another brand and trying that. If that fails, I might take it to an armorer or grind down the catch so it has more travel, but I really want to solve the problem, not the symptom.

>>688581

the bolt catches on MILSPEC AR type rifles are generally not very stable, that is why most people rarely carry a round in the chamber, and only fools carry a mag in with bolt to the rear. There were also several variations of "milspec" catches throughout the years, the most recent having a larger cross section to prevent inadvertent release IIRC. post pics and we might be able to help.

Even though it might seem stupid, what kind of buffer do you have in there right now? Some parts kits are sold with 9mm buffers, and there is a difference between the springs and buffers for SBR ARs and long barreled "rifle" ARs.

It is possible that there is just enough room where the bolt catch does not seat right because the pocket for it was over-milled/ not cut out enough. pictures could explain it better.

I see 80% Glocks, AR15s, AKs, 1911s, and P320s. Why aren't there more 80% versions of guns? Is it a patent problem? Getting lower parts from the manufacturer? Manufacturers not endorsing it? Too complex for the average person? It would be nice to see 80% revolvers and shotguns. There's one 80% shotgun and it's ridiculously expensive. The lower alone costs as much as a new shotgun from a store.

>>688629

A lot of it is the ATF. What does 79% look like? 81%? The ATF have turned down quite a few ideas because they're not like the other ideas they've ok'd.

Some of it is parts availability. I'd love to make PSL, but there just aren't any whole parts kits out there, and almost nobody makes suitable parts such that, as with the AR, you could buy a part a month, each from a separate vendor, until you have everything but the receiver.

And lets not underestimate the fact that most people are lazy and/or stingy. Many firearms could be constructed from 50% kits, but who has both the tools to finish them, and the engineering gumption to carefully do so correctly?

Lastly revolvers look dumb, so I'm not with you there. But something that isn't encumbered because it's not something else? How about a bull-pup AR-ish pistol? Or a belt fed krinkov? That'd be nifty. But no, no one will help me build something that isn't incredibly popular, so Joe Public is a poopyhead. So there.

(I agree though – more variety is appropriate. But Tactical Machining makes a 10/22 clone, and of course there's the AR10/LR208, not just the -15 blanks.)

>>688657

I get a partial hold or no hold at all with both the magazine and manually pressing the nub.

When trying to manually lock the bolt, I am pulling the charging handle all the way back and holding it, then pushing and holding the nub, then gently moving the handle back until it catches, and then letting go.

I have never seen the catch do any better than snag the very tips of the bottom two lugs in any situation except for when I used a punch that was smaller than the roll pin in place of the roll pin. When I did that, the catch didn't come up as high as I've seen it in pictures of working ARs, but it was probably high enough to do the job. The only thing that tells me is that the upper receiver probably isn't interfering with the catch. I doubted that was the issue but I've heard of one case.

>>688658

Try just holding the bolt catch then charging the rifle with the nub down, that might help. Also does it rise correctly with the upper removed and a magazine inserted?

It does not actually need to snag too much, as long as it consistently holds. I am assuming you built this from an 80% lower? Sometimes those have design flaws, and I would investigate if the outside of the receiver is filed down/open enough to allow the catch to move all the way (pivot into side - up onto bolt).

>>688665

It seemed to move the same with and without the upper on. I tried holding the catch up by the nub while closing the upper on top of it and if the catch was pushed down, it wasn't enough to be noticable.

I'm not sure what holding it up while charging would do. Wouldn't the back of the bolt run into it?

It is an 80% reciever. I actually just got a new buffer retainer and tried to install it because I did something stupid and broke the first one. It didn't fit, not even close. I tried the retainer from an oops kit I bought, same thing. I tried the original and found the fit was so close that the retainer trapped some air under it, and it acted like an air spring even without the regular spring under it. I had to sand it down, removing the coating completely, to get the new one to fit. At this point, I'm fairly sure the lower is out of tolerance in multiple areas.

I got a new catch with the other parts I ordered and it actually works. It doesn't sit as high as the catch in some pictures I've seen but it functions correctly. I'm going to stick with this. I'll let the company know what happened, and I plan on trying 80%s from 5D Tactical next, although if anyone has recommendations I'd love to hear them. At least I finally have a 100% functional rifle.

>>688696

>I'm not sure what holding it up while charging would do. Wouldn't the back of the bolt run into it?

because of the slanty edge on the front of the catch, the bolt rides over it, then locks on the forward motion. as long as you have 100% retention on bolt return, rifle is fine.

Almost every part of an AR should be able to be installed with bear hands, the only parts that need torque wrenches/special tools are the nut that holds the barrel on, and the buffer tube. Carbine style buffers are a little harder to install because of the plate that nees to be set before a nut can be placed to tighten it down. The only punches you need are the punches for installing pins, everything else just takes patients and good dexterity.

Out of curiosity, what kind of 80% brand were you using so other anons can try to avoid it?

IIRC I used an Anderson arms bare aluminum for my first build, but I accidentally the hole wrong (made it too big), and the first time I shot the rifle, my trigger pin actually popped out of my gun at the range. I just picked it up and put it back in, but I will make sure the next 80% I do I actually try to drill the holes straight through. The first time the left and right sides were not aligned, so I just made the hole bigger to make the pin level with the trigger, that was a mistake, but I had very little machining experience at the time.

Also do not use spray can high temp paint, because it melts off when it comes in contact with CLP. On the other hand, I have a receiver that looks like it saw actual combat ¯\_(ツ)_/¯

>>688707

The lower was from Noreen, but I want to contact them first before making any judgements.

Made a polymer80 glock 19 with an RMR, oem parts, brownell frame and slide. I need to redo half of the trigger pin hole because it’s a little wider than it should be (jb weld). Shoots fine though.

Has anyone had success with Norcal's P365 kits?

At Shot Show PSA announced a 299 dollar Glock clone (350 for suppressor height sights+threaded barrel+optics cut). In an interview with AKOU they confirmed they'll be offering build kits for Polymer 80s. In an interview with Hank Strange they confirmed the "lower assembly" (might be including lower parts, unclear) alone will sell for 99. Also mentioned in another interview (forget where) this would be launching in ~60 days.

What color should I do? I wanted to do Robin's Egg Blue+stainless when parts became cheaper, but that color of Polymer80 has been discontinued.

>>684856

are there any places to get aluminum frames for a glock? All the places I see only sell polymer frames

i just decided to start an g19 that looks like the pistol from halo. i was putting off 3D printing a glock but i saw that and it seem unique and cool enough for me to give it a shot. after that is done im definitely going to start the FGC9

Now that I've assembled all the parts (I thought) it turns out that the barrel I bought online was … you know, TECHNICALLY a conversion barrel for the glock 35.

Sitting in the g-17 slide, I had to mill a bit of metal out but now it sits pretty in the slide. And catches pretty hard on the locking block, preventing me from racking the slide. This means even if it fired (seems to sit in battery but I don't have the lower parts in yet) it wouldn't cycle even slightly.

Thoughts? Anybody have both a 35 & 31( or 17) barrel to compare lugs?

How does one forge a shovel head to be an AK reciever?

>>689875

with a car-oil fired forge, a large sledge hammer, and a too-conveniently sized anvil.

What are the most recommended places to order parts for my 1st build? Also, what would be a good choice for my 1st build?

>>689892

A hardware store, and a break barrel shotgun. Need a welder though, pipe shotguns are fine also.

>>689858

getting closer?

I've made attempts to put the lower parts kit into the frame. Know what I had trouble with? The locking block.

Actually that's not true – The big trigger hole was directed by the jig, and the hole and the locking block don't line up. Or didn't. Since I could get an undersized steel punch through, I squeezed the drill bit back through, and both polished the inside of the 'block, and removed more plastic. Pin fits, all seems to be well. Probably.

>>689934

GRRR

I ordered a spring. It says it's for the 17, 17lbs. It … sits in the slide. I'm mostly assuming that's because they somehow shipped me an RSA for the glock 19?

If GET this running, I'll probably build a glock-32 also. But if I don't … I'm going to give up on Poly 80 and the whole glock franchise.

>>684997

Just buy it off Amazon.
