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 and the thread pitch is 1/2x36, which matches the included black 9mm 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 Vertex Enhanced Pistol Caliber dedicated AR-9 billet aluminum upper receiver carries an anodized finish with a full-length Picatinny top rail for optics and accessory mounting. The 10-inch ultra-slim KeyMod freefloat handguard is black with KeyMod 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 AR-9 nitride 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.
