The Aero Precision .308 Winchester Bolt Carrier Group is a complete, drop-in BCG for AR-10 and .308-pattern rifles. This aero precision .308 bcg arrives fully assembled with a mil-spec phosphate finish and is MPI and HPT tested, so it is ready to run as the firing mechanism for a large-caliber build. It sits alongside the rest of our FRT trigger parts and build components as a duty-grade upgrade.
A bolt carrier group is an ordinary rifle part. Always follow your state and local laws, and you must be of legal age and eligible to purchase.

Built for big-bore AR-10 builds
The 4340 steel extractor uses double O-rings and double springs for reliable extraction under pressure, and the external surfaces are CNC ground after heat treatment for a precise fit. Forward assist serrations and a laser-engraved Aero Precision logo round out the carrier, a level of finish you will see echoed across the full AR-15 and AR-10 trigger range. Each group ships with the bolt carrier, complete bolt, firing pin, cam pin, and retaining pin.
