Barrel and Muzzle Device

The 7.5-inch contour profile barrel is chambered in 5.56 NATO with a manganese phosphate finish, 1:7 right-hand twist rate, and 1/2x28 thread pitch, which matches the included A2 birdcage flash hider. A black 1/2-inch crush washer, a micro low-profile steel gas block at 0.750 diameter, and a pistol-length gas tube cover the front end gas configuration on this pistol-length platform.

The 7-inch freefloat smooth tubular handguard covers the barrel and provides the front end interface on this compact AR-15 pistol platform. These two components define the exterior structure of the upper assembly.

The USA-made complete AR-15 bolt carrier group is compatible with 5.56 NATO, .223 Remington, .300 Blackout, and .350 Legend. A Mil-Spec AR-15 M4 charging handle is included to complete the upper component set.
