The Warne Shotgun Rib Reflex Mount is a revolutionary new mount design that allows shooters to mount various reflex style red dot optics to most vented rib shotgun barrel. Many popular shotgun models are not drilled and tapped for a conventional scope base or rail, Warne's proprietary clamp design attaches directly to a vented rib barrel and allows for a low profile universal mounting plate that fits most popular reflex sights. While The Warne Shotgun Rib Reflex Mount is great for turkey, waterfowl and upland bird hunting, it is equally effective for clays, competition and tactical use.
