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