For Quick Detach/Reattach Of Scope Without Loss Of Zero
One-piece riser mount with integral rings provides additional elevation from top of rail to centerline of ring to ensure a proper cheek weld. Precision machined from aluminum bar stock for a secure fit on flattop receiver rail. Scope and mount form a single unit for fast attachment and removal without loss of zero. Mounts by hand tightening the oversized thumb screw to clamp the locking plate. The captive, spring-loaded locking plate maintains a positive mechanical connection that resists loosening under shock and vibration. Four hardened Torx®-head screws clamp each ring cap to the lower half. Models available for scopes with 1" or 30mm diameter bodies. 1" and 30mm model’s forward cantilever lets the scope overhang the front of the receiver to ensure plenty of eye relief.
