This compact and versatile AR-15 upper receiver is fully assembled—just add a BCG and charging handle to complete your build. It features a flat-top M4 forged Mil-Spec receiver, precision CNC-machined from durable 7075-T6 aluminum for maximum strength and reliability.
The 5-inch .300 Blackout barrel, crafted from 4150 Chrome Moly steel, offers a 1:5 twist rate and a Micro gas system, delivering reliable performance and smooth cycling with subsonic or supersonic loads. Outfitted with a standard A2 flash hider, this upper effectively reduces muzzle flash in low-light conditions.
