Product description
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!

I see in the description that it works with the EndoMags, but how about the Mean Arms ExoMag?
Brian · Jul 28, 2025AT3 Support Team — Since the ExoMag is designed to be compatible with standard blowback 9mm BCGs that fit Glock or Colt variants (which AT3's 9mm BCG supports), the AT3 Tactical 9mm BCG should work with the Mean Arms ExoMag as well.
