High-Quality Black Nitride Bolt Carrier Group For Your 9mm Build

This AT3 Tactical™ 9mm Bolt Carrier Group features meticulous machining and a high-quality finish for a lifetime of use. This bolt makes a great partner for any Glock or Colt-compatible AR-15 blowback barrel, so you can make a completely custom build to suit your needs.

The black nitride finish features excellent hardness and lubricity, which means this BCG is durable, easy to clean, and less reliant on lubrication.  It weighs in at 14.6 ounces total, and has a removable rear weight for compatibility with JP and Armaspec recoil springs.

MPI Inspected With Enhanced Geometry

The AT3 Tactical™ 9mm Bolt Carrier Group receives magnetic particle inspection (MPI), and includes properly staked grade-8 gas key screws. With its enhanced geometry, this BCG shares compatibility with Glock, Colt, and Endomag extractors.  Whether you’re running a proprietary lower or an adapter with those styles, this BCG will work for you.

This high-quality BCG will ensure a reliable rifle function and is guaranteed to last a lifetime. Made in the USA!
