Bought 2 Polymer 80% AR-15 lower receivers today!

Looks like a last resort to me.

Ummm. Wow that looks odd, looks like the FCG pocket is filled in with different material. Who's the manufacturer? Thing looks very rough. Best of luck!!!

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.

Tagged, that looks WEIRD.

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.

Ten Percent out of Kern county has one in a raffle on gunbroker.com I saw them when I read the front page of their website and followed the gun broker link.

There is a company and write up

Complete not 80 percent

I don't know what the heck those are... but I wouldn't let my ex-wife fire one.

Unless I was really far away.

I wouldn't touch one of these with a 10 foot pole.

Yah... uhh that looks absolutely terrible. Is someone buying $25 airsoft guns and filling the FCG and calling it a polymer 80%?

[Jason_2111]

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..."

That's exactly what it looks like to me too

[Jeepers]

That's exactly what it looks like to me too

yup must be a airsoft otherwise it would not be legal even if its a reject it was never "demilled" and was complete at one time .....

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:
