We've done it again. Heavy Walled Lighter Weight Upper Receiver precision machined from 7075 T6 Billet Aluminum. Much stiffer and stronger than a Forged Upper. Very close attention to detail is evident in this upper. Each Unit is serial numbered to help with quality control and responsibly of our machine Techs and goes through a comprehensive 25 Step Quality inspection. Each unit is engraved with 7075 so there is no question as to what material we are using. The bore through center is Roller Burnished to create a smooth surface for the carrier system. The Shell deflector is positioned at 60 Degrees and is slightly curved to help with deflection while reducing damaged brass. Notice relief cuts along rail to help prevent damage to rail when mounting accessories (no more white lines along edge of rail). Bolt catch area is enlarged to allow for use of ambi or extended bolt releases.

Also Includes M4 Feedramps!
