Bootleg bcg - Bootleg Inc Lightweight Adjustable Carrier, AR 15, Stripped, Semi Auto ONLY

while being really good quality, this bolt carrier didn’t fit in either of my upper receivers. i have an Aero Precision Enhanced and an Arsenal Democracy billet uppers, both of which fit all my other carriers fine. the adjustment knob on the backside of the carrier rubs and doesn’t allow it to slide in or out. i’m not here to bash Bootleg, just letting people know to do research before you buy
