Reptilia ROF Diving Board Mount Fits AUS/ Geissele Super Precision Anodized Finish FDE 34mm. Manufactured at the request of a DoD customer the Diving Board places a MIL-STD-1913 rail at the ideal position and height to mount laser range finders such as the Wilcox RAPTAR laser designators or miniature red dot optics on a NightForce ATACR 5-2556 F1 ATACR 7-3756 or ATACR 7-3756 F1. Additionally the Diving Board doubles the support area on the optic tube by reusing the ring cap from the host mount. While it has been optimized for use with the NightForce ATACR it is compatible with a wide range of other higher power magnified optics such as the Vortex Optics RAZOR HD GEN III 6-3556 FFP or the Tangent Theta 5-2556 and 7-3556.
