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., 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 freefloat 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.

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 configuration.
