Barrel and Upper Receiver

The 7.5-inch HBAR profile barrel is 4150 CrMoV steel with a phosphate finish and a 1:10 twist rate. The muzzle is threaded at 1-in-2x36 and pairs with the included KAK Plan B Radial Brake, which supports modular suppressor mounting ecosystems compatible with the Plan B platform. The Freedom Factory Tactical dedicated AR-9 upper receiver is 7075-T6 forged aluminum with a Type III hard coat anodized finish, serving as the core front end structure for the AR-9 build. The AR-9 platform operates via blowback.

Handguard

The tubular freefloat M-Lok handguard is aluminum in black, keeping the forend lightweight and compact. The tubular profile maintains a slim, clean forend, and the M-Lok slots provide attachment points for lights, grips, and other accessories. The handguard length is shorter than the 7.5-inch barrel, and the muzzle device extends beyond the handguard to provide the necessary clearance.

Bolt Carrier Group and Charging Handle

The included 9mm bolt carrier group is built from 8620 alloy steel with a nitride finish. This BCG is the correct unit for AR-9 blowback-operated configurations. The mil-spec M4 charging handle completes the upper component set.

SB Tactical SBA5 Brace and Buffer System

The SB Tactical SBA5 pistol stabilizing brace pairs with the included mil-spec heavy-duty 6-position buffer tube. The 5.5 oz buffer, mil-spec receiver end plate, lower parts kit, and all associated buffer system hardware cover the core lower completion components outside the serialized lower receiver.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
