The Reptilia ROF-45 is a drop-in upgrade for magnified scope mounts. Available initially for Geissele Automatics' Super Precision 30mm optic mount, it adds a mounting point for a Trijicon RMR 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.Features:Machined from billet 7075-T6 aluminumMIL-STD, Type III, Hardcoat anodized27 grams
