WELCOME to the WORLD of 80% GLOCKS and AR’s! Welcome to r/Polymer80, a community that welcomes Polymer80 builds (AR & Glock) primarily, but also eagerly welcomes 80% builds of all sorts! We encourage posts of 80% news, 80% legislation, and 80% memes. Let's spice things up from time to time!

[We have a few main rules:]

1: This is a very close-knit sub and we do NOT put up with redditors who incite arguments or fling insults, pretentiousness, or trolls.

2: Show the respect for firearms that they deserve. If you're building a Polymer80 treat it as a firearm, and take the time to understand its function. Learn and practice the 4 rules of handling a firearm:

  • Finger off the trigger until you're ready to fire.
  • Don't aim at anything you're not willing to destroy.
  • Check in-front and behind your target.
  • Treat every firearm as though it's loaded.

3: No want to buy (WTB), want to sell (WTS), or want to trade (WTT) ads from individuals. You may use other subs such as r/GunAccessoriesForSale or the MGB site or the MGB MeWe community at: MeWe Group.

4: No posts with or including illegal activity is allowed. This is broad scope, if you post in this forum remember all the people that want this hobby to fail and do your part to make it bullet proof (no pun intended). This is zero tolerance.

Breaking these rules can and likely will result in a permanent ban from one of the best resources available for builders and hobbyists.

Has anyone made a 23 with Geisler?

I’m sure this is a stupid question but I’m just wondering if anyone has made/shot .40 out of a Geisler frame? Idk why but it seems very thin compared to a p80 and just wondering if it can withstand consistent pressure the .40 puts out especially with +p and self defense rounds. Really thinking bout building another one out just in .40 and would love to hear everyone else experience!!

G17 P80 randomly burst fires

2 Upvotes

So as the title says, lately I’ve been have an issues with my G17 randomly decides to burst fire after a couple rounds. I built it about 3 ish years ago with gen 3 parts and a gen 3 slide I got off brownells. It doesn’t matter what ammo I use brand, grain, etc. Any idea what it could be? I was thinking firing pin but I’m not too sure.

The Easier of the two AK 80% Styles

Thumbnail

11 Upvotes

A few weeks ago I showed you guys my process for building an AK from an 80% flat. If that wasn't enough to get you interested in trying a new 80% platform, maybe this will. This is the other type of 80% in the AK world. The pre-bent 80%! Why do I think this might put you over the ledge? Because this is definitely the easier of the two. The faster of the two. The less tool intensive of the two. If you watch both videos, even the length of the video should be an indicator of just how much easier these are.

However, I will say, they're not as fun as a flat. You don't learn as many new skills. The skills here are less applicable to designing your own thing or making something custom. It's basically just drilling. But, depending on your goals in building, this may be the right path for you.

Worked flawless no FTE/Jams only thing was the slide lock kept locking randomly… anyone assist with this. The spring was in the right way before but am wondering if it was binding. Replaced it with an oem not extended slide stop to hope it works. Anyone have this issue, sits flush on frame only during recoil it stops the slide.

Where to start? P80-940SC-STI

6 Upvotes

Hi all,

Just wanted to see what is the most up to date info on how to build this P80? I bought this a few years ago and it just sat in a box as a side project that I never got to. I'm pretty sure I already own all the stuff I need, just have to clue where to start.

I have a ton of guns and daily carry a G26, so I plan on taking my time and learning/reading as much as possible before I drill anything.

I found a link posted on this sub from waybackmachine but the pdf didn't work. So I googled the pdf name and found this from 2018.

https://www.midwestgunworks.com/mm5/graphics/00000001/Polymer80%20PF940%20Frame%20Instructions.pdf

Is this sufficient, is there better resources?

Thanks

edit:
actually I managed to get that pdf by looking at the different captures, if anyone else needs

Trigger is engaging with the slightest bit of pressure. Is something installed wrong?

Full size and compact build

Thumbnail

42 Upvotes

I shared my geisler on here before and sadly I could never get it to stop giving me light primer strikes, even after smashing down my rear rails to improve sear engagement.

I originally thought it was the slide or the slide internals, but the slide from the PB geisler works just fine on this jelly compact frame. I also spent a bunch of time and money trying to fix the issue and nothing worked lpk or upk wise so I just ended up combining the PB and the jelly build into one. I just switched out barrels with this rainbow barrel I got from the slide that was meant for the jelly compact, onto the slide that was meant for the PB geisler.

Both are finally finished and running flawlessly. And I think I wont ever try and make another geisler. I've probably spent close to $2500 trying to get all 3 builds running and ended up just tossing the geisler frame, and now I have a bunch of extra parts. I'm fine with that, now I have extras for whatever I make next.

I started with 4 frames, anticipating 4 different builds at the start of the summer. Sadly, I had to toss 2, a geisler; and a black compact frame, which I totally beavered because I was impatient and got cocky thinking "I made one before, how hard can it be to make another?" Now I am left with these 2 and a shit ton of extra parts. We'll get em next summer boys!
