Quality product - Faxon Gen 2 9mm PCC Blowback Full-Mass Bolt Carrier Group, Glock/Colt Compatible

I did quite a bit of research prior to purchasing a bcg for a AR-9 since I know they can be troublesome to run smoothly. Faxon came up often as a quality choice. Mine is excellent, solid construction and I have had no problems so far The only thing I wish is more of these 9mm bcg wouldnt have seperate piece unneeded "gas key" and instead the whole thing being one solid piece. Some bcg are this way, but most arent. Mine was properly staked and wont be going anywhere anyway. Would definitely recommend. Plus, their costumer service is great. I've emailed them for other products and they respond with detailed information within a day.
