The mounting surface on the super precision scope mount spans 7 Picatinny sections and utilizes 4 shear lugs. These mounts use geissele's update of the classic nut and bolt method for clamping the mount to the Picatinny rail, which is the most secure method of attaching your scope to your weapon. Each nut and bolt combination provides 1,400 pounds of clamping force, much more than any lever mounting arrangement. The Geissele super precision mounts are available in 7075-T6 high strength aluminum. To create a mount with the best possible return to zero we machine the entire mount from a single piece of billet aluminum. This allows us to add pockets and ribs throughout the mount for added strength and rigidity. It allows us to line bore the caps to each another and then serialize the caps to the body. The line bore operation creates the best possible fit to the body of your scope so that you can apply proper torque without fear of crushing or damaging the body of your scope. Another advantage of machining from a single piece of aluminum is that we are able to create a mount with cap locations that will suit a wide variety of scopes. These mounts will be available in standard, extended, and Hyper extended lengths. All mounts will also be available in zero and 20 MOA cant options, available in either black type 3 hard coat anodize or our proprietary Ddc (Desert dirt color) type 3 hard coat anodize.
