Barrel and Muzzle Device

The 10.5-inch medium profile barrel is chambered in 9mm and constructed from 4150 CrMoV steel with a nitride finish. The twist rate is 1:10 right-hand 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 AR-15 billet upper receiver for pistol calibers carries a black finish and is designed around the AR-9 pistol caliber platform. The 7-inch aluminum tubular freefloat M-LOK handguard is black with a 1.77-inch internal diameter providing suppressor-ready clearance, and 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.
