LEAP/09 State of the art 34mm scope mounts. Designed for shooters who want the lightest, stiffest, and easiest to use quick-detach scope mount possible. The LEAP/09 base incorporates different structural elements to maximize overall performance. A large diameter tubular section up front to resist torsion from side impacts, and a very wide I-beam bridge in the rear to resist recoil induced oscillations. Every Leap mount is CNC milled from 7075-T6 Aluminum billet, which has vastly superior mechanical properties to 6061-T6, and is used where ultimate strength and durability outweigh cost considerations.
