Built using our 18" 4150CMV barrels produced in house, air gauged and borescoped to ensure top quality accuracy. This free float upper lends itself to an increase in accuracy by not putting pressure on the barrel and the mid-length gas system softens the recoil allowing faster follow up shots. Our uppers are built from the ground up to be fast, accurate and reliable. Now being offered as a complete package with bolt carrier group and charging handle ready to pin to your lower and hit the range!
