KAK Industry AR-15 Barrel Features The KAK Industry AR-15 Barrel is built from chrome moly vanadium steel a material chosen for its strength and heat resistance under sustained firing. The chrome-lined bore and phosphate exterior finish work together to resist corrosion and extend the barrel s service life compared to an untreated bore. A 1:7 twist rate gives this 16 barrel the stabilization needed for heavier 5.56 projectiles alongside standard weights making it a versatile option for a range of shooting applications. The 1/2x28 threaded muzzle accepts standard AR-15 muzzle devices from flash hiders to compensators. KAK Industry was founded to address a gap in the market for quality American-made AR components at affordable sustainable prices. This barrel is a direct fit for AR-15 platform rifles giving builders and owners a straightforward path to replace a worn barrel or complete a new build. Its 16 length keeps the rifle maneuverable while still delivering the velocity and accuracy shooters expect from a mid-length barrel. Weighing just under 30 ounces it s a practical no-frills upgrade for any AR-15 project.
