Bolt Carrier Groups

ar15-bcg-for-sale.jpgThe bolt carrier group is the heart of any AR10/AR15/M4/M16 type rifle, carbine or AR pistol.  Bet-your-life dependability is a non-negotiable prerequisite. We carry Aero Precision, Toolcraft, Fail Zero and Spike's Tactical BCGs with Nickel Boron, Black Nitride, Ionbond DLC, Chrome/Magnesium Phosphate and Titanium Nitride-Gold finishes with M16 profile carriers. Chances are we have the AR BCG that you are looking for. See our Bolt Carrier Group Buyer's Guide.
