Hi guys:



I was given a flat top stripped upper.  The issue is that there's no manufacturer's marks on it ANYWHERE (I've even taken a scope to the inside).



My question for the experts is:  does it matter what bolt carrier and bolt I put in the upper?  There are a myriad of manufacturers and honestly I'm kind of lost.



Thanks sincerely in advance!

Nope go for whatever.  I would go with either a LMT or BCM bolt carrier group though.  The seem to be about the best.

+1.  BCM's are what I primarily use, though I would use an LMT as well.  I've used CMT/Stag and they were fine, but I didn't like how the carrier key was staked in them.  I also have a mutt gun that uses an Armalite bolt and have no problems with it.
