Barrel and Muzzle Device

The 10.5-inch barrel is chambered in 9mm and constructed from stainless steel with 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 ultra-lightweight minimalist freefloat M-LOK handguard features anti-rotation tabs and provides 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.
