Geissele Automatics 05-418B Super Precision 34mm Hyper Extended

The AR-15/M4 Super Precision series of scope mounts are optimized for use with an AR-15/M4 upper. The mounting surface 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 made from 7075-T6 High Strength Aluminum. The entire mount is machined from a single piece of billet aluminum. This allows pockets and ribs throughout the mount for added strength and rigidity. It allows Geissele to line bore the caps to each other 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 to create a mount with cap locations that will suit a wide variety of scopes.
