Barrel and Muzzle Device

The 10.5-inch barrel is chambered in 9mm with a black nitride finish and a 1:10 twist rate. The thread pitch is 1/2x36, which matches the included A2 birdcage flash hider. A black crush washer is included with the muzzle device. At 10.5 inches this barrel keeps the overall upper compact while covering the front end from muzzle device to upper receiver.

Upper Receiver and Handguard

The upper receiver is 7075-T6 aluminum with an anodized finish, M4 feed ramps, an AR-15 style ejection port cover, and a forward assist. The 10-inch ultra-lightweight minimalist freefloat M-LOK handguard features a partial top rail and no anti-rotation tabs, providing M-LOK attachment points along the body for accessory mounting. These two components define the exterior structure of the upper assembly on this AR-9 platform.

9mm Bolt Carrier Group and Charging Handle

The 9mm nitride bolt carrier group is 8620 alloy steel with an external extractor, compatible with both Glock and Colt pattern magazines. A Mil-Spec AR-15 M4 charging handle is included to complete the upper component set.
