Shout out to BCM, if you need parts for your build, BCM is where it's at.

I agree as well. I use alot of BCM parts, all trouble free, highly reliable. Only 2 complaints I've ever heard about BCM is inability to post negative reviews on their website and the bolt carrier issue awhile back where customers were complaining about the tool chatter in non critical area of the bolt carrier. I saw a couple of those and they were cosmetically real ugly. I would have sent them back if I had received one with that degree of chatter too. That issue has been resolved and those that wanted replacements got them.
