Barrel and Muzzle Device

The 6-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 1/2x28, which matches the included muzzle-mounted fake can in 6061-T6 aluminum. At 6 inches this barrel produces a highly compact overall upper length while covering the front end from muzzle device to upper receiver.

Freedom Factory Tactical Upper Receiver and Handguard

The Freedom Factory Tactical dedicated AR-9 upper receiver is 7075-T6 forged aluminum with a Type III hardcoat anodized finish. The receiver is designed specifically around the AR-9 platform and includes an AR-15 style ejection port door with rod and spring. The 10-inch freefloat M-LOK handguard is aircraft-grade aluminum with an anodized finish, providing 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 platform.

9mm Bolt Carrier Group and Charging Handle

The 9mm nitride bolt carrier group is 8620 alloy steel with 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.
