The Warne shotgun rib reflex mount introduces an innovative design that enables shooters to mount various RDS (red-dot sight) optics with the ARCO interface onto most vented rib shotgun barrels. Many popular shotgun models lack drilled and tapped conventional scope bases or rails, so Warne's proprietary clamp design securely attaches directly to vented ribs ranging from 6 to 10mm wide. This mount features a low-profile universal mounting plate compatible with most popular Mini RDS sights. Ideal for a wide range of applications, including turkey, waterfowl and upland bird hunting, as well as clays, competitions and tactical scenarios, the Warne shotgun rib reflex mount offers versatility and reliability for enhancing aiming precision with shotgun optics.
