Reptilia ROF-Diving Board, originally for 34mm Geissele Super Precision Magnified Optic Mounts, is also compatible with Reptilia 34mm AUS Mounts. The Diving Board places a MIL-STD-1913 rail at the ideal position and height to mount laser range finders . 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.
