“The GAP Mount” Made on request from George Gardner of GA Precision. Special mount with extra low height. Due to the low height it will not work with scopes like S&B 5-25 and 3-20, the Kahles k624i, or Vortex Razor as the erector housing will collide with the bridge between the rings. It works fine with Bushnells and S&B 3-12×50 and 4-16×50. Aiside from the low height a special feature of this mount is an extra front clamping screw allowing the SP-4011 to be mounted partly forward – in a cantilever position – on the Picatinny rail of the action. This is especially useful on AR-type rifles and actions with integrated Picatinny rails like Defiance, Surgeon and Impact, where the rail isn’t sufficiently long for the desired eye-relief with some scopes. 0 MIL/0 MOA Height: 28 mm/1.102” Clearance: 5.5 mm/.216″ (from the bottom of the tube to bridge of the mount body) Length: 121 mm/4.76” Weight: 231 g/8.1 oz 10-degree wedge included
