AT3 9mm Nitride BCG + Breek Warhammer AR-15 Charging Handle

Save on this bundle to take your PCC build to the next level, with a reliable 9mm bolt and excellent charging handle for your AR-9 upper. We’re discounting our black nitride 9mm bolt carrier group, and pairing it with one of the most popular charging handles in our store! Choose the lever size of the Breek Warhammer that fits you best to improve your rifle’s ergonomics, while maintain stellar reliability.

This kit is great for finishing out an upper build, and you can save even more by bundling our Upper with M-LOK handguard, or Upper with Quad Rail if you’re starting fresh. Be sure to look out for a 9mm barrel as well. The AT3 9mm BCG also works with AR-9lowers that have Colt or Glock pattern ejectors built in, when you’re looking for 9mm magazines.

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!

Breek Arms Warhammer AR-15 Charging Handle – Standard and Micro Levers in All Colors

If you’re looking for a charging handle upgrade that’s above and beyond the mil-spec, with features that rival the big brands, at a price that really can’t be beaten?  Look no further than the Warhammer from Breek Arms.  Not only does it make your AR15 truly ambidextrous, but the Warhammer also has thin, deep-set handles to ensure it doesn’t interfere with optics or backup sights, making for an even slicker experience than other handles out there.

Very impressed so far!

Bought this set to go in our Aero EPC-9 LEO demo build and we are very impressed with the quality and durability of both the AT3 bolt the Breek Arms CA. The rifle these parts are in went into torture testing immediately and have stood up over 500 rds of suppressed bulk 124 grain 9mm FMJ and has yet to have a failure.

Thanks for sharing your feedback! We're glad you are satisfied with your purchase!
