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 Vertex Enhanced Pistol Caliber billet AR-9 upper receiver carries a black finish and is designed around the AR-9 pistol caliber platform. The 10-inch freefloat M-LOK handguard is black 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.

Bolt Carrier Group and Charging Handle

The complete 9mm blowback bolt carrier group is 8620 alloy steel with a nitride finish and features 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.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify compatibility with your specific 9mm AR-9 lower receiver and magazine pattern before use.
