"I run Colt uppers on my AR-15s. Took a chance with MI bolt carrier group and it is very well put together. Took it out yesterday and put 150 rnds of AAC 300 Blackout and it ran them through like a buzz saw. I would put this up against any bolt on the market. You want a quality BCG at a affordable price buy one. Lifetime warranty doesn't hurt either."
