This Bravo Company Manufacturing AR-15 Standard M4 Barreled Upper Receiver is built to Mil-Spec. Each entire upper assembly from BCM® is constructed to stringent standards and test-fired, then headspaced. BCM uses a method of Parkerizing the components before putting them all together that ensures precise quality control during the assembly of each upper. The BCM standard upper is perfect for building a USGI M4 style civilian clone. The Mil-Spec 11595E 12.5-inch government profile barrel is high pressure/magnetic particle inspected and features a manganese phosphate finish for toughness. The Bravo Company Manufacturing Standard Barreled Upper Receiver Group has the M4 carbine style delta ring that will accept a variety of drop-in hand guards and an A2 front sight for a reliable aiming point.
