Proven KAK Industry Barrel

The 11.5 inch barrel from KAK Industry uses 4140 CrMoV steel with nitride finish for wear resistance and corrosion protection. The 1 in 8 twist stabilizes most common bullet weights, and the government profile balances weight with heat management. Threaded 1/2x28 for standard muzzle devices.

Complete Upper Assembly

This upper ships with the bolt carrier group and charging handle already included. The BCG is built from 9310 alloy steel with nitride finish for smooth cycling and easy cleanup. The mil spec charging handle gives you reliable function. Upper receiver is 7075 T6 aluminum with M4 feed ramps and anodized finish.

M LOK Handguard System

The 10 inch freefloat handguard is machined from 6061 T6 aluminum and finished in black. M LOK slots run the length for lights, grips and other accessories. The freefloat design improves accuracy by eliminating pressure on the barrel. Lightweight construction keeps the front end balanced.

Carbine Gas Configuration

Carbine length gas system is optimized for the 11.5 inch barrel length. The micro low profile gas block sits at 0.750 diameter and keeps a clean look under the handguard. This gas setup provides reliable cycling with a wide range of ammunition and keeps felt recoil manageable.

Follow safe handling and manufacturer instructions at all times. Ensure compliance with all applicable laws. Lower receiver not included, BCG and charging handle are included with this complete upper. Verify compatibility with your lower receiver and intended configuration before installation.
