Aero Precision Ar15 5.56 Bolt Carrier Group No Logo - Black Nitride

The Aero Precision AR15 5.56 Bolt Carrier Group in black nitride is a precision-engineered component built for shooters who demand reliability without fuss. This no-logo BCG is machined from 8620 tool steel for the carrier and 9310 steel for the bolt, delivering the durability you need whether you're running a dedicated 5.56 rifle or a multi-purpose build. The black nitride finish is an advanced lower-friction coating that minimizes the need for constant lubrication and cleaning—a practical choice for shooters who want less maintenance downtime and more trigger time.

Like all quality Aero Precision BCGs, this one features M16-cut carrier geometry, forward assist serrations, and a properly staked gas key for reliable operation. The bolt is shot peened and MPI tested to catch any internal flaws before they reach your rifle. You get a mil-spec extractor with a black o-ring insert and Viton seal for consistent performance across thousands of rounds. Every detail—from the gas key staking to the shot peening process—reflects Aero's commitment to no-nonsense precision.

Whether you're assembling an upper from scratch, replacing a worn BCG, or building a spare bolt carrier for rotation, this group handles both range duty and field use without pretense. No logo means a cleaner, understated look; no compromise on function.
