Barrel and Muzzle Device

The 5-inch slim profile barrel is chambered in 9mm and constructed from steel with a parkerized 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 1/2-inch crush washer is included. The direct blowback platform design addresses the 9mm cartridge in an AR-9 pistol caliber build.

Upper Receiver and Handguard

The 7075-T6 aluminum upper receiver carries an anodized black finish with M4 feed ramps, an ejection port door with rod and spring, and a forward assist assembly. A full-length Picatinny top rail runs across the top of the upper receiver for optics and accessory mounting. The 4.2-inch freefloat M-LOK handguard is 7075-T6 aluminum in black with an integrated hand stop 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.

Bolt Carrier Group and Charging Handle

The complete 9mm 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 lower receiver before use.
