One for the AR15 experts
I just came into a Bushmaster Carbon 15. It's a recent production gun with forward assist, dust cover and standard AR internals.

Does anyone know for sure the relative durability of the composite lowers on these guns? I want to use it with my 458 SOCOM upper but thought I would check with you gurus first. Thanks.

I'm thinking they are not highly recommended, but you might wait and see what the others say.

Your not going to break anything with that caliber !. Ask Bushmaster .

space-age Carbon 15 composite molded Receivers for light weight and rugged durability.

Upper & Lower Receivers molded of durable, water resistant Carbon 15 Composite with Operational Controls same as any AR15 type firearm. Color Coded Safety Lever markings on both sides of Receiver for quick visual check of firing condition.

I don't think the 458 SOCOM is the issue. But I don't have much NICE to say about the "Carbon 15"!

Good luck. Bud! Wink

Thanks. I fooled around with one of the original PO Cabon 15s a long time ago and wasn't impressed. This is the newest model with forward assist and dust cover. Got my fingers crossed. I put an A2 stock on it already and that made it more tolerable. I'll put up a review after I get a few hundred rounds through it.


P.S. The trigger sucks. Standard Bushmaster trigger group but not too impressive.

All the stresses during firing are on the upper, so a polymer or carbon fiber composite lower is no problem.

I use PlumCrazy lowers; their triggers are excellent.

Plumcrazy lowers are fast developing a reutation for failure. If I wanted light and simple I would use Cavalry Arms lowers.

That's too bad because they're quite reasonably priced.

I hope they can work the bugs out of the carbon fibers because a reliable, feather light AR would be sweet!

Please provide specific information (no anecdotes, please). I have seen a picture of a Carbon 15 lower (not PlumCrazy) that split at the mag well, but there were no details appended, i.e., how did it split, what happened to the upper, etc.).

Day two of a PD hunt and about 800 rnds and all is good so far. Got a week of shooting to go.

Theres a thread about them at Lightfighter. Maybe M4C. Pictures were included to back up the anecdotes. The stories and pictures weren't pretty.

Pictures are gone. The story is worrisome but like so many of the gun blow-ups onthe net (and in person), there's no way to determine precisely to what extent it was the gun or the ammo or other outside force.

Regardless, I don't think this will be the end-all and be-all of AR platforms for me.
