View Full Version : Bought 2 Polymer 80% AR-15 lower receivers today!

Bought two polymer "paperweights" today at gun show in Ontario... that's right POLYMER not aluminum. Came with few bucks to spend everything I was looking for was sold out decided I fork over $150 for two pieces of plastic :facepalm: Last summer I successfully turned 80% aluminum lower receiver into a 100% using my drill press and cant wait to start on this polymer one. Posted this to see if anyone here has ever had any experience with building, drilling or milling a polymer 80% lower receiver for AR-15? I did a Google search on the internet and couldn't find much info. Of course due to the high demand of paperweights the companys website down due to heavy traffic. I'm thinking once I finish this 80 percent lower I'm probably going to make it into dedicated .22, it being "plastic" aka "polymer" and all. Anyhow glad I bought two just in case I screw up on the first one. But come to think of it any screw ups could probably be fix with a little epoxy.

Looking forward to any pics, tricks or experiences shared. Thanks in advance.

only tip i can give you is when milling it out take time and be careful as plastic melts where the aluminum cuts away into shavings. plastic doesnt do that so dont let it get to hot when doing this.i hope it makes sense on what im trying to tell you.

Who made it and who was selling it! Plastic 80s would be great, even now the production should be fast and the normal cost should be around $20. Are there markings on it?

Make sure they have some metal in them....I don't know what falls under the undetectable firearms laws, but you'd best know.
IMHO, plastic lowers are going to be in the same history chapter as aluminum wiring.

I'm working all day till around midnight and honestly I cant stop thinking about getting started :D I'll take pictures and post them as soon as I can. As for who makes these polymer lowers I have no clue, I think theyre made by guy/company I bought them from but there was no info on the 80% lower its self. I picked up the business card at the booth but didn't bring it to work with me so I don't have the contact info. Once I get home I'll provide as much info as I can.

I'd love to hear about past experiences with polymer 80% lowers so I don't end screwing something up. I searched the internet like crazy last night and couldn't find anything. Perhaps its something new?

I'm always extremely leery of anything bought "at a gun show"... home of the chinese knock-off 80%s and other such not-sellable on the open internet things.
I'd really like to see pictures of these polymer's, and find out where they came from.

Cutting them shouldn't be any more difficult than an aluminum 80%... the question is whether they'll last for more the 10 shots.

I don't know. Even if everything else was plastic, you'd still have enough metal in the barrel alone to not be considered undetectable. But if the regs, however they are written, will apply to a frame or receiver by itself, that might be an issue ???
I don't know how the law or the regs are written, so I don't know. I don't know about those lowers specifically, but other polymer lowers I've seen have metal plates in them where the serial number is.
....just pointing out that it is something that should be looked into....

Just so you know, those plastics are NOT undetectable. They show up easily on the current scanners, although the current law stated:


"Undetectable Firearms Act of 1988 - Amends the Federal criminal code to make it unlawful to manufacture, import, sell, ship, deliver, possess, transfer, or receive any firearm: (1) which is not as detectable as the Security Exemplar (after the removal of grips, stocks, and magazines) by walk-through metal detectors calibrated and operated to detect the Exemplar; or (2) of which any major component, when subjected to inspection by x-ray machines commonly used at airports, does not generate an image that accurately depicts the shape of the component.

Defines the term "Security Exemplar" to mean an object that is suitable for testing and calibrating metal detectors and is, during the 12-month period beginning on the date of enactment of this Act, constructed of 3.7 ounces of stainless steel in a shape resembling a handgun. Directs the Secretary of the Treasury, at the close of such 12-month period and at appropriate times thereafter, to promulgate regulations to permit the manufacture, importation, sale, shipment, delivery, possession, transfer, or receipt of firearms that are as detectable as a security exemplar which contains 3.7 ounces of stainless steel or such lesser amount as is detectable in view of advances in state-of-the-art developments in weapons detection technology."


So its a complete gun, of which 3.7 oz of metal which can be sensed by a metal detector needs to be there. Not a stripped receiver. If you made one, with the plastic LPK, carbon stock, plastic upper, carbon tensioned barrel, you still have to deal with a bolt carrier. If someone makes a .22 bolt carrier out of plastic, then you may be under that 3.7 oz

It looks like someone took a COMPLETE polymer lower and just filled up the fire control pocket with epoxy... But that wouldn't explain the plastic flash on the magwell. What are those shiny stickers covering the maker's markings? I'm guessing your friend put those on there, but if they came like that when you bought them, I wonder what's underneath...

Ah well, nothing to do but finish them up and go see how well they hold up.

I'll bet they were originally mfg as complete polymer lowers but didn't make it past inspection. Somebody bought them in bulk for cheap, filled in the FCG pockets to make them 80% lowers, then hoped to cash in on the fact that 80% lowers were going for MORE than complete lowers were for several months now.

This does raise an interesting proposition for you. Perhaps it is possible to DISSOLVE whatever gunk was used to fill up the pocket, rather than mill/drill it out. I don't know what solvents would work without also damaging the polymer, but it is still a real possibility, especially if that's epoxy.

With all of the garbage that floods the market as prices get rediculous, it wouldn't surprise me in the least to see someone taking crappy chinese airsoft receivers, filling them with epoxy, and trying to unload them on GB or at a gun show.

You guys wouldn't believe some of the garbage we've seen come through our build party, and it's always the same story... "Got this at a gun show..."

The one I sold him is not as pretty as the one I kept, but he liked the black one. The one I kept has a smooth top and is made from a white polymer. The white polymer one felt a lot stronger and tougher (it passed the jumped on it/hit it with a mallet test). I sold him the "ugly" since he offered to pay half of what I spent. I'm Hoping to get off early today to take much better pics of mine and post as soon as I can. It feels pretty strong but even then I'm thinking of using it with magazine well "grip" installed like one of the one below...I've seen these polymer lowers break in the front area of the magazine well before:

Saw that EP Lowers is claiming to be the original 80% Polymer JIG-LESS lower and thats not true at all unless this company is also know as DIYLOWER. The lowers I purchased last winter and posted on here had two different colors letting you know what to remove out of the FCG. EP lowers is claiming something I can vouch is not true. Maybe you guys are the same company in that case my bad. As for the lowers... well I screwed up due to being too excited to get it done and the other one that went to a friend is his boys dedicated .22. I'll probably get another one from DIYLOWER or EP Lowers once I get some free time so I can take slower this time around.

I'll make it into a .223 pistol for my wife, or register it as an AW and let her have an SBR. something fun like that. My next aluminium 80 will replace the current one I have, and my current one will become a dedicated bolt lower.

Ep lowers has them is stock. Polymer80 does not (and still hasn't satisfied pre orders). DIY I don't know, as I couldn't find a site for them.

And FYI, the lowers you bought do not appear to be jigless. The FCP may have been a different color, but I see no markings, guides, or color differentiation for the selector hole or either of the pin holes. That means you would have to jig up, use a pattern, or measure before drilling those holes. The ep lowers have guide posts with divots at the end to make it truly jigless.

Pics on the first page aren't showing, but you should see two pictures on the second. I don't think OP got EP lowers because they have a fixed trigger guard. His have the standard open guards, plus no fire rate markings or guide pins/divots (from what I read, early ep prototypes had starter holes, then they moved to posts to ensure 80% status).

I got in touch with DIYLower.com (http://www.diylower.com) over the phone about getting another polymer 80% and they said they've put a pause on orders for now because they are "working on something much bigger that will change the entire gun industry". Got kinda excited and I asked for more info and was denied. So it looks like I'll have to order some from either EPLowers.com (http://www.EPLowers.com), Polymer80.com (http://www.Polymer80.com) and or this new place I found called Poly80.com (http://www.Poly80.com) I'll probably get one from each vendor to compare them and post my pictures and findings.

Polymer lowers aren't bad at all.
I picked up this Bushmaster Carbon a few years ago at Turner's in Chino Hills. Looking at the lower and bolt carrier, I was a little concerned but the sales guy assured me it was as durable as aluminum.
Since then my sons an I fired hundreds and hundreds of rounds without any problems at all. What I really like is the finish, it doesn't get shiny with the normal scratches and scuffs.

I have the same problem. Never had any issues with my aluminum 80s I have done. Don't rely on their markings they were wrong on mine.

Perpendicular nothing. I know it was done correctly I used the drill press and the mill and have done others. Just make sure you measure correctly.
