Barrel and Gas System

The KAK Industry 11.5-inch barrel is chambered in .223 Wylde and constructed from 4140 CrMoV steel with a government profile and a 1:8 twist rate. The nitride finish covers the full barrel surface for corrosion and wear resistance. The muzzle is threaded 1/2x28 and includes a GI birdcage flash hider. The carbine-length gas system pairs with a micro low-profile steel gas block at .750 O.D. with a phosphate finish, a separate component positioned beneath the handguard on the barrel.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum with an anodized finish. The 10-inch black aluminum tubular M-Lok handguard provides M-Lok slot access along its length for accessory mounting without contact with the barrel or gas system components.

Bolt Carrier Group and Charging Handle

The complete bolt carrier group uses a 9310 alloy steel bolt with a nitride finish, compatible with 5.56, .223, .300 Blackout, and .350 Legend configurations. The included mil-spec AR-15 M4 charging handle meets mil-spec dimensional standards for use with the upper receiver included in this kit.

SB Tactical SBA3 Stabilizing Brace

The SB Tactical SBA3 adjustable pistol stabilizing brace is included as the brace component for this pistol-format full build kit. The SBA3 features a 6-position adjustable design compatible with the mil-spec heavy-duty buffer tube included in this kit. It is intended for AR-15 pistol-format configurations.
