The Super Precision ACOG Series was developed specifically to work with the Trijicon 4x power ACOG series of optics. These mounts are precision machined from a single piece of 7075-T6 high strength aluminum. They will also be available in black type 3 hard coat anodize as well as our proprietary DDC (Desert Dirt Color) type 3 hard coat anodize. Utilizing Geissele’s update of the classic nut and bolt method, this mount will attach your ACOG to your weapon with 2,800 pounds of clamping force, and features 4 shear lugs for maximum rigidity and return to zero.
