This rail replaces the standard Ruger Scout Rifle Rail with a full length Picatinny rail, which extends back over the receiver to allow more scope mounting options for this popular rifle.
NB: We would like to advise our customers that some different scope ring brands are not compatible with this rail, predominantly Leupold & Warne rings. They have been found to not close or tighten sufficiently onto the rail due to the length of closure available on the clamp mechanism. Arctic fox rings have been checked and DO NOT have this issue. We have also checked the integral bases on our Arctic fox Red Dot and Electrodot rifle scopes and they tighten sufficiently onto the the Ruger Scout Rifle rail.
