GUN cracked lower :wtc:

The part of the lower where the stock screws into has a small crack at the 12 oclock position.

It's a bushmaster carbon 15 lower (plastic). It's spread out about 1mm apart, and when I try to move the stock and spread the gap, it doesn't budge.

How would I go about fixing this? Or do I have to get a new lower?

 

New lower. Talk to BM, they'll probably warranty it.

 

wow. don't post this on arfcom. they'll never believe it

 

Gorilla glue and or JB weld should have it good as new.

 

PROTIP : Get an aluminum lower.

 

I thought carbon was stronger?

so I was told anyway

 

Haven't you personally seen evidence to the contrary?

 

Call Bushmaster and see if it's under warranty.

Then sell it and buy a real AR

 

I wouldn't use Gorilla Glue. Go to the hardware store though and get some "2 Ton" epoxy, that should take care of it, although if you can post pictures I could give you a better idea.

Unless the company will warranty it for you.

 

I was obviously kidding

 

Wasn't obvious to me. I'm good at fixing broken composites.

 

good epoxy would probably do it, I've fixed alot of composite stuff too, never carbon though only times I've broken that it shattered beyond repair

 

Oh, guess I shoulda put a smiley face

For something like that I'd be putting whatever kind of warranty was available into use.

 

care to enlighten me?

 

Your lower is broken, kid

 

I got it used, maybe it was abused by previous owner .

 

Any AR15 should take recreational abuse, if that lower can't, ditch that shit asap.

 

I was toying with the idea of a Carbon-15 in 9mm for a nice lightweight AR, but shit like this worries me.
