Barrel and Handguard

The 16-inch Tactical Match barrel is constructed from 4150 chrome moly vanadium steel in an M4 contour with a phosphate finish, cryo treatment, and a 1-in-8 twist rate. The thread pitch is 1-in-2x28, corresponding to the included GI birdcage flash hider. The carbine-length direct impingement gas system pairs with a 0.750-inch gas block positioned beneath the handguard. The 15-inch freefloat M-Lok handguard is made from 6061-T6 aluminum in black and keeps the handguard clear of the barrel along its full length.

Upper Receiver and Bolt Carrier Group

The Black Diamond Series slick side billet upper receiver is made from 6061-T6 aluminum with a Type III hard coat anodized finish and is manufactured in the USA. The bolt carrier group is made from 8620 alloy steel with a nitride finish, compatible with 5.56, .223, .300, and .350 configurations, and is also manufactured in the USA. The included AR-15 M4 mil-spec charging handle pairs directly with the upper receiver and bolt carrier group.

Stock and Lower Components

The special operations stock pairs with the included mil-spec buffer tube as part of the complete lower component set. This kit includes a lower parts kit, buffer, recoil spring, end plate, and castle nut, providing the components needed to complete a stripped lower receiver. The lower receiver itself is not included.
