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

The Black Diamond Series slick side billet upper receiver in this kit is constructed from 6061-T6 aluminum with a Type III hard coat anodized finish, 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 low-profile gas block corresponds to the pistol-length gas system configuration included in this kit.

7-Inch Freefloat M-LOK Handguard

The 7-inch freefloat M-LOK handguard in this kit is constructed from aluminum. 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 full handguard surface.
