How strong is HDPE?

[NSR500]

This guy built an AR15 lower out of HDPE (High Density Polyethylene): http://www.weaponeer.net/forum/forum...035&PN=1&TPN=3



Looks like the damn thing runs too!



You guys think I can make a Masada out of it?! LOL!!!

[jumbopanda]

LOL that's hilarious!

[RedDawn]

Nice!

as long as the buffer tube thread area is strong the AR will work. The rest could be made out of top ramen, it doesn't see much stress

[C.G.]

Heavier than aluminum.

This reminds me of the wood AR lower.

Why just not use Bushmasters Carbon lower? It seems like it would be the lightest.

I know cutting boards come in black as well .

It wouldn't have been nearly as cool if it weren't for the fact that he made it out of "welded" up chunks of cutting board.

I'd hate to be holding that thing when it melts, which it will eventually.

[bohoki]

that would really match well with the air force 22 conversion kit

With a melting point of 266*F, I doubt it.

You haven't seen me tear up the range with my CAR (reg. of course).

Your receiver doesn't get that hot.

The AR receiver sees so little stress.

I'd only worry about the extension and what would happen with a KB.
