Warne RMR Red Dot Reflex Mount Features The Warne Red Dot Reflex Mount uses a proprietary clamp design that attaches directly to a vented rib shotgun barrel between 6 and 10mm wide eliminating the need for drilling and tapping a receiver that was never designed for a conventional scope base. This low-profile universal mounting plate is compatible with a long list of popular reflex sights including Burris Fast Fire 2 and 3 C-MORE RTS and STS Docter Eotech MRDS Holosun 507c/407c in both V1 and V2 versions Leupold DeltaPoint and DeltaPoint Pro Shield RMS Sig Romeo 3 Romeo 3 Max and Romeo 3 XL and Trijicon RMR footprints. That broad compatibility means shooters already invested in a particular red dot pattern can likely mount it directly without buying a different optic. Machined from black anodized aluminum and designed and made in the USA the mount measures 12.6 inches long and just 1.2 inches tall keeping the shooter s sight picture low and natural along the rib. It ships complete with mounting hardware for a secure no-fuss installation onto the barrel. While the Warne mount is especially suited to turkey waterfowl and upland bird hunting where fast target acquisition matters it performs just as well for clays competition and tactical shotgun applications. This versatility makes it a smart upgrade for any shotgun owner looking to add red dot speed to their existing vent rib barrel.
