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 micro low-profile gas block positioned beneath the handguard. The freefloat tubular M-Lok handguard is made from aluminum in black and keeps the handguard clear of the barrel along its full length.

Upper Receiver and Bolt Carrier Group

The upper receiver is constructed from 7075-T6 aluminum with M4 feed ramps and an anodized finish. The bolt carrier group is made from 9310 alloy steel with a nitride finish, is compatible with 5.56, .223, .300, and .350 configurations, and is manufactured in the USA. The included AR-15 M4 mil-spec charging handle pairs directly with the upper receiver and bolt carrier group.
