Barrel and Gas System

The pistol-length gas system pairs with a micro low-profile 0.750 gas block to cover the gas regulation side of the upper. A GI Birdcage flash hider at 5/8x24 rounds out the muzzle end.
Upper Receiver and Handguard
The upper receiver is 7075-T6 aluminum with an anodized finish, forming the structural core of the upper assembly. The freefloat M-Lok handguard is aircraft-grade aluminum in black, surrounding the barrel without contact and providing M-Lok mounting positions for compatible accessories.
Bolt Carrier Group and Charging Handle
The included bolt carrier group is 9310 alloy steel with a nitride finish, made in the USA. The BCG and Mil-Spec M4 charging handle work together to cycle the action and complete the upper side component set.
Buffer System and Rear Hardware
The buffer system consists of a Mil-Spec heavy-duty 6-position buffer tube, a 3 oz standard carbine buffer, and a recoil spring. A Mil-Spec receiver end plate and castle nut complete the rear hardware included with this full build kit.
