Bolt Carrier Groups

The bolt carrier group is the heart and soul of any AR15/M4/M16 type rifle, carbine or AR pistol.  Bet-your-life dependability is a non-negotiable prerequisite. We carry Toolcraft and Fail Zero BCGs with Nickel Boron and Black Nitride finishes with M16 profile carriers. Chances are we have the AR BCG that you are looking for. See all AR15 parts here: AR15 Parts
