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 12-inch MX10 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 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.

SB Tactical SBA3 Pistol Brace and Buffer System

The SB Tactical SBA3 adjustable pistol stabilizing brace is included as the brace option for this pistol configuration. The mil-spec heavy-duty 6-position buffer tube pairs with the SBA3 brace for AR-15 and AR-style pistol configurations. The kit also includes a 3 oz standard carbine recoil buffer, a carbine recoil spring, a mil-spec end plate, and a castle nut.
