The AR-15/M4 Super Precision series of scope mounts are specifically designed for optimal compatibility with AR-15/M4 upper receivers. The mounting surface extends across seven picatinny sections and incorporates four shear lugs. These mounts employ Geissele's enhanced version of the traditional nut and bolt method for securing the mount to the picatinny rail, recognized as the most reliable technique for attaching a scope to a firearm. Each nut and bolt assembly delivers 1400 lb of clamping force, significantly surpassing any lever-based mounting system. Constructed from 7075-T6 high-strength aluminum, the Geissele Super Precision mounts are engineered for maximum return to zero by machining the base from a single piece of billet aluminum. This manufacturing process enables the integration of pockets and ribs throughout the mount, enhancing its strength and rigidity. Additionally, machining the mount base from a single aluminum piece allows for versatile cap locations, accommodating a wide range of scopes. Nut and bolt clamp design - this advanced design optimizes grip strength and durability, ensuring secure fastening and improved performance The picatinny rail system provides a standardized mounting platform for attaching various accessories to firearms, ensuring compatibility and secure attachment Type III hardcoat anodized coating is a durable, corrosion-resistant surface treatment that enhances the wear resistance and longevity of metal components
