Barrel and Handguard

The 11.5-inch KAK Industry barrel is constructed from 4140 CrMoV steel in a government profile with a nitride finish and a 1-in-8 twist rate. The thread pitch is 1-in-2x28, corresponding to the included steel flash can with a black oxide finish. The carbine-length gas system pairs with a 0.750 steel micro low-profile gas block positioned beneath the handguard. The Trinity Force Echo Keymod 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 an anodized finish. The bolt carrier group is made from 9310 alloy steel with a nitride finish and is compatible with 5.56, .223, .300, and .350 configurations. The included AR-15 M4 mil-spec charging handle pairs directly with the upper receiver and bolt carrier group.
