Barrel and Gas System

This upper uses an 11.5 inch barrel made from 4140 CrMoV gun steel with a Nitride finish and a government profile, manufactured by KAK Industry. The 1:8 twist rate is suited to a wide range of .223 Wylde bullet weights, and the 1/2x28 thread pitch matches standard AR-15 muzzle device threading. A carbine length gas system runs to a micro low-profile gas block sized for a 0.750 outer diameter. The barrel and gas components make up the front end of this complete upper.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum and finished with a durable anodized coating. It features M4 feed ramps for reliable feeding geometry. A 10 inch freefloat MLOK handguard made from 6061-T6 aircraft-grade aluminum in black with a Type III hard coat anodized finish surrounds the barrel without contacting it, giving this upper its exterior forend structure.

Bolt Carrier Group and Charging Handle

The included bolt carrier group features an 8620 alloy steel body and a 9310 alloy steel bolt head, both finished in Nitride, and is rated for 5.56, .223, .300, and .350 chamberings. A Mil-Spec quality M4 charging handle completes the cycling components of this upper, rounding out the included hardware.
