Black Diamond Series Billet 6061-T6 Upper Receiver and .300 Blackout Barrel

The Black Diamond Series slick side upper receiver in this kit is constructed from anodized 6061-T6 billet aluminum, distinguishing it from standard forged AR-15 upper receiver configurations. The 6-inch .300 Blackout barrel is constructed from steel with a nitride finish and a 1:7 twist rate. The micro low-profile gas block corresponds to the pistol-length gas system configuration included in this kit.

7-Inch Freefloat M-LOK Handguard with Picatinny Top Rail

The 7-inch freefloat M-LOK handguard in this kit includes a partial Picatinny top rail section, providing a dedicated optic or accessory mounting surface along the top of the handguard. The freefloat profile keeps the handguard clear of the barrel for an unobstructed fit along the upper assembly. M-LOK compatibility supports modular accessory attachment across the remaining handguard surface.

Gauntlet Arms Brace and Bolt Carrier Group

The Gauntlet Arms polymer stabilizing brace is a recognized pistol stabilizing brace option within the AR-15 pistol platform. The complete bolt carrier group and muzzle device with 5/8x24 thread pitch are included components within this pistol full build kit. The 5/8x24 thread pitch on the muzzle device corresponds to the .300 Blackout platform thread specification.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
