Barrel and Muzzle Device

The 5-inch slim profile barrel is chambered in 9mm and carries a parkerized finish with a 1:10 twist rate and 1/2x36 thread pitch, which matches the included black oxide steel Flash Can Design 11 Rev 2 Pattern 2 muzzle device. 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 AR-15 and AR-9 compatible forged slick side upper receiver carries a black anodized finish and removes the forward assist housing from the upper receiver body for a clean exterior profile. The 7-inch Super Light Series 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 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.

Lower Parts Kit and Buffer System

The complete Mil-Spec AR-15 lower parts kit covers the internal lower receiver components.

The SB Tactical SBA3 adjustable pistol stabilizing brace in black pairs with the included Mil-Spec carbine buffer tube and covers the rear brace interface for this AR-9 pistol lower build kit.
