Barrel and Muzzle Device

The 5-inch slim profile barrel is chambered in 9mm with a parkerized finish. The twist rate is 1:10 and the thread pitch is 1/2x36, which matches the included 9mm A2 birdcage flash hider. A black 1/2-inch crush washer is included. The direct blowback platform design addresses the 9mm cartridge in an AR-9 pistol caliber build without a gas system.

Upper Receiver and Handguard

The 7075-T6 aluminum upper receiver carries a black anodized finish with M4 feed ramps, a forward assist, and an ejection port door assembly. The 4-inch Honeycomb freefloat M-LOK handguard carries an anodized grey finish with 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 pistol platform.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included. Verify compatibility with your specific 9mm AR-9 lower receiver and magazine pattern before use.
