Geissele Super Precision 34mm Hyper Extended Scope Mount 05-418B was designed for use on AR-type uppers and delivers one of the most secure mounts available. The mounting surface takes up 7 Picatinny sections and features 4 shear lugs with 2 nut-and-bolt combinations. Each of the nut-and-bolt combinations provides a clamping force of 1,400 pounds, which is far more than a lever mount can manage. That force is what keeps this Geissele Super Precision Scope Mount locked down even under heavy recoil. To ensure the best possible fit and return to zero, the mount is milled from a single piece of high-strength 7075-T6 aluminum. That single-piece construction allows Geissele to add ribs and pockets throughout for enhanced strength and rigidity, and it lets them line-bore the caps to each other before serializing them to the body. This Geissele 34mm scope mount setup ensures proper torque can be applied without accidentally crushing or damaging the scope's tube. At a 1.54" centerline height, this is Geissele's Hyper Extended configuration, built for larger optics that need extra clearance over the receiver.
