The Reptilia ROF-45 is a drop-in upgrade for magnified scope mounts. Available for the Geissele Automatics Super Precision optic mount, it adds a 45Adeg mounting point for a Leupold DPP to provide a fast, close-range optic to your magnified scope. Each ROF model is designed to minimize each optic's distance from the host scope's centerline, while ensuring enough clearance that the sight picture isn't obscured. Mfg: Reptilia Corp
