The carbine-length gas system uses a .750 O.D. micro low-profile gas block in steel, positioned beneath the handguard.

The upper receiver is 7075-T6 aluminum with M4 feed ramps and an anodized finish. The freefloat M-Lok handguard is 6061-T6 aluminum in black, providing a clean forend with M-Lok accessory slots along its surface. The handguard length matches the 10.5-inch barrel, with the muzzle device providing clearance beyond the handguard.

The included bolt carrier group is a complete AR-15 unit built from 8620 alloy steel with a nitride finish, made in the USA. It is compatible with 5.56 NATO, .223 Remington, .300 Blackout, and .350 Legend configurations. The mil-spec M4 charging handle completes the upper component set.

SB Tactical SBA5 Brace and Buffer System

The SB Tactical SBA5 pistol stabilizing brace is black and pairs with the included mil-spec heavy-duty 6-position buffer tube. The 3 oz carbine buffer, lower parts kit, and all associated buffer system hardware cover the core lower completion components outside the serialized lower receiver.
