Barrel and Handguard

The 14.5-inch barrel is constructed from 4150 CrMoV steel in a government profile with a phosphate finish and a 1-in-7 twist rate. The thread pitch is 1-in-2x28, corresponding to the included GI birdcage flash hider. The carbine-length gas system pairs with a 0.750 gas block positioned beneath the handguard. The 12.5-inch freefloat tubular M-Lok handguard is made from aluminum with a 1.77-inch internal diameter and a suppressor-ready profile, keeping the handguard clear of the barrel along its full length.

Upper Receiver

The upper receiver is constructed from 7075-T6 aluminum with M4 feed ramps and an anodized finish. It pairs with the barrel and handguard included in this kit. A BCG and charging handle are not included with this upper build kit and must be sourced separately.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included.
