Aero Precision 5.56 Nitride Bolt Carrier Group

Aero Precision makes high-quality parts suitable for any build, and this BCG is no exception. This part features a slick, easy-to-clean black nitride finish and a 9310 steel bolt that’s been high-pressure tested (HPT) and magnetic particle inspected (MPI). Along with an 8620 steel carrier with a properly staked gas key, this BCG makes a suitable starting point for building or upgrading the existing rifle.

Why Black Nitride?

Black nitride finishes are industry standard treatment for bolt carrier groups and barrels. This process increases surface hardness and lubricity, adequately replacing rough phosphate finishes and expensive chrome plating. Nitride strikes the perfect middle ground, making an excellent choice for various shooters and making maintenance simple.
