Upper Receiver and Barrel

The 7075-T6 aluminum upper receiver with an anodized finish and M4 feed ramps forms the core of the front end, with a Mil-Spec forward assist assembly and an AR-15 ejection port door assembly built in. The 10.5-inch HBAR profile steel barrel brings a Parkerized finish and a 1-8 twist rate to the .300 AAC Blackout chamber, threaded at 5-8x24. The pistol-length gas tube and micro low-profile steel gas block at .750 inch run a tight pistol-length gas system along the barrel, well-matched to the 10.5-inch barrel profile.

Trinity Force FW P1812 KeyMod Handguard

The Trinity Force FW P1812 12-inch freefloat KeyMod handguard surrounds the barrel and gas system along the forend with anti-rotation tabs for a secure fit at the upper receiver and a full-length top Picatinny rail running the entire 12-inch length of the handguard for continuous optics and accessory mounting from the upper receiver forward. The KeyMod mounting system runs along the handguard body for accessory attachment at additional positions across the forend. At 12 inches the handguard extends beyond the 10.5-inch barrel, giving the front end a clean and extended profile on this pistol-length build.

Muzzle Device

The Steel Flash Can Design 4 in black oxide threads onto the 5-8x24 muzzle end of the barrel and closes out the front of this pistol-length upper with a flash can profile that is noted as compatible with 9mm and .350 Legend at this thread pitch. The included black 5-8-inch crush washer seats at the barrel shoulder and completes the muzzle hardware for this kit.
