Product description

Unwavering Reliability with KAK’s Mil-Spec 16″ 5.56 Barrel

This 16-inch 5.56 NATO barrel brings proven military-grade performance to your AR-15 platform. Constructed in-house from certified 41V50 chrome moly steel, the bore is precision-honed and air-gauged to ensure tight tolerances.

A rugged nitride finish provides extreme corrosion and wear resistance, even during heavy use. The medium government profile maintains quick maneuverability while the rifle-length gas system enables smooth, consistent cycling.

Expect match-grade accuracy thanks to the fast 1:7 twist rate, optimized to stabilize both 55-grain and heavier 5.56 projectiles. Weighing under 30 ounces, this barrel combines rock-solid durability with light, balanced handling characteristics.

For next-level reliability and accuracy, equip your AR with this Mil-Spec 5.56 barrel proudly manufactured in the USA. Experience KAK Industry’s unwavering quality and precision first-hand.

Oversized gas hole which is good for rifle length on 16 inch. Good price. The coating is legit. Mounted up fine. Yet to shoot it. will for sure use adjustable gas block and would recommend that to any buyer of dissipater barrel unless going for GI build, if so, adjust ejection angle with buffers.
