Barrel and Muzzle Device

The 7.5-inch M4 contour barrel is chambered in 10mm and constructed from 4150 CMV steel with a Parkerized finish. The twist rate is 1:16 and the thread pitch is 9/16x24, which matches the included A2 birdcage flash hider compatible with 10mm and .40 S&W. A black crush washer is included with the muzzle device.

Billet PCC Upper Receiver and Handguard

The 6061 billet PCC upper receiver is 6061 aluminum with a black anodized finish, purpose-built around the AR-15 pistol caliber platform. The Airlite honeycomb series 7-inch freefloat M-LOK handguard carries a black anodized finish with a honeycomb skeletonized profile and honeycomb lightening cuts along the handguard body. M-LOK attachment points run along the body for accessory mounting, and the full-length Picatinny top rail provides a continuous optic and accessory mounting surface. These two components define the exterior structure of the upper assembly on this 10mm platform.

Bolt Assembly and Charging Handle

The PCC blowback bolt assembly is compatible with 10mm and .40 S&W on this platform. A Mil-Spec M4 charging handle is included to complete the upper component set.

Lower Parts Kit and Buffer System

The complete Mil-Spec AR-15 lower parts kit covers the internal lower receiver components. The buffer system includes a Mil-Spec heavy-duty 6-position buffer tube, an 8 oz buffer in black, a USA-made standard AR-15 carbine recoil spring, an AR-15 M16 Mil-Spec end plate, and an AR-15 carbine castle nut. The SB Tactical SBA3 adjustable pistol stabilizing brace in black pairs with the included Mil-Spec 6-position buffer tube and covers the rear brace interface for this pistol lower build kit.
