Is this manufactured by BCM?
Michael S on Jun 26, 2019
BEST ANSWER: BCM doesn't manufacture BCG's, they subcontract them. The big premium you pay is for the specs and the logo.
They might be made AO Precision. Another company was selling one very similar, I'll update when I get mine and compare.
Does this have a o ring on the ejector ?
Daniel M on Jun 26, 2019
BEST ANSWER: On the extractor. Yes it does.
Does this bolt have a tool steel extractor?
Donald S on Jul 1, 2019
BEST ANSWER: Just Carp 158, through and through. But, can't be definite on that.
does this mean with this you can make the ar15 full auto ?
casey o on Jun 26, 2019
BEST ANSWER: it means that if you have a modified fire control, sanctioned by the powers that be of course, that allows for full auto then this bcg has potentioal to accomodate that, you need to have full auto fcu stowed away first. Good luck and hope this helped

has anyone had a headspace problem with these?
oilcan dan on Jul 6, 2019
BEST ANSWER: Pass'd the GO and NO GO. But that's more based on your barrel not on the BOLT carrier.
Is it ready to go out of the box?
Jaygarza on Oct 20, 2019
BEST ANSWER: You may need to clean some of the grease off of it and re clean it they last two I have ordered had a lot of packing grease because they tend to sit on the shelf for a while before shipping out.
Would the BC work in a semi auto? No plans to convert to full auto..
James K on Jul 1, 2019

Great BCG for the money.
Looked over the lugs to be sure there were no irregularities. Checked the rings for a nice snug fit. Checked the gas key for proper staking. So far, functions like a dream. Time will tell.
