Barrel and Gas System

This kit uses a 16.5 inch barrel made from 4150 Chrome Moly Vanadium Steel with a Nitride finish and a government profile. The 1:7 twist rate is suited to a wide range of .223 Wylde bullet weights, and the 1/2x28 thread pitch matches the included GI birdcage flash hider. A mid length gas system runs to a micro low-profile gas block sized for a 0.750 outer diameter barrel. The barrel and gas components make up the front end of this upper build kit.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum and finished with a durable anodized coating. A 15 inch ultra-lightweight minimalist handguard made from aircraft-grade aluminum, finished in Type III hard coat anodize, surrounds the barrel without contacting it, completing the exterior forend included in this kit.
