Barrel and Muzzle Device

The 4.5-inch medium profile barrel is chambered in 9mm and constructed from 4150 CrMoV steel with a nitride finish. The twist rate is 1:10 and the thread pitch is 1/2x36, which matches the included black A2 birdcage flash hider. A black 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 6061 billet pistol caliber AR-15 upper receiver carries a black anodized finish. The 4-inch Guntec Honeycomb freefloat M-LOK handguard is gold with honeycomb lightening cuts along the body and M-LOK accessory slots for accessory mounting. The gold handguard provides a distinctive color contrast against the black anodized upper receiver. 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.
