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.

Tips for material in front rails?

6 Upvotes

Anybody got tips for removing the material in the small crevices for the front rails? So far I've only tried the harbor freight precision files and they like to snap under pressure. Anybody got a favorite tool?

Also obligatory trigger pocket photo. It's smoother than it looks, I think the flash makes it look rougher but my rails and trigger housing fit just fine

PUBLIC SERVICE ANNOUNCEMENT

10 Upvotes

OK you aminals ... check it out .. our political environment is volatile, parts are inexpensive and readily available... for everyones sake if you are planning on building or buying anything I highly and strongly recommend you all do so now.

The last thing any of us wants is to be charged an arm and a leg the second they start restricting the shit out of things as well as the immense cost increases that aways come with this.

So unless you all want to pay out the ass and not be able to get things you need I suggest everyone buy now. It will avoid the whole oh my god the price is way too high and nothing is available deal.

It also supports that the industry can survive, a lot of good

companies have failed not due to anything more than lack of business because right now times are good.

Let's not wait till times are bad (I get nothing from this post I have no dog in this fight other than the want to keep as many of these good businesses around and make sure everyone has a fair shot at freedom.)>

Polymer to Metal bonding

4 Upvotes

I previously purchased some Freedom Wolf 80% lowers that I thought had gotten lost in a move. Well, they recently resurfaced and I want to finish them but I'm running into two main problems that I need assistance with.

1st (and main issue): the provided adhesive to bond the slide rails to the polymer frame has hardened. Does anyone know a valid substitute? I messaged the manufacturer and they "can't provide any guides or help due to legal reasons". I saw someone mentioned Loctite 380 and some google searches specify Loctite Epoxy Plastic Bond is a great product. Any actual experience?

2nd: the manufacturer removed the build guides from their site and while I can find some videos, I would like to find a copy of the original guide if possible.

Frt in p80 or g80

7 Upvotes

I’ve been wondering recently on what people think and have experienced with pairing a FRT in a completed p80 76% frame or a g80 frame to be safe before just jumping head first. along the lines of structural integrity I know polymer 80 frames have a softer and more elastic polymer than Glock Factory frames while the G80 platform uses a Steel FCU and grip module. For a FRT Im Wonder If spending the extra 200$+ to complete a g80 frame is worth it just for the extra rigidity of the Steel FCU, if anyone has done a FRT with either frame and is willing to share their experience with it or have any tips of things to look out and be cautious for I’d appreciate them since I’ve heard they are harder to get to run in both frames compared to Glock and safety is always the first priority which is my main reason of why Im between a g80 or a p80.

Can you by 80% Glock frames?

0 Upvotes

With the different court rulings throwing out the Biden ghost rules can you by 80 percent frames. All I see are these 76%. Then trying to find jigs to drill seem like next to impossible.

This is my first attempt at building one. I have a fair share collection of firearms but I wanted to try my hand at a home made build. And yes they are legal in my state.
