Barrel and Handguard

The 5-inch BC-9 barrel is constructed from 4150 CrMoV steel in a slim profile with a phosphate finish and a 1-in-10 twist rate. The thread pitch is 1-in-2x36, corresponding to the included 9MM flash can with a manganese phosphate finish. The 7-inch freefloat M-Lok handguard is made from aircraft-grade aluminum in black and keeps the handguard clear of the barrel along its full length. This kit is blowback-operated and does not use a traditional gas system.

Upper Receiver

The upper receiver is constructed from 7075-T6 aluminum with 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.
