EGW Guns Sight Mount Features This EGW Guns sight mount is designed to replace the rear sight on compatible Ruger pistols providing a stable dovetail platform for a Vortex Razor C-More RTS or C-More STS red dot sight. Machined from aluminum and finished in black the mount measures 1.831 inches long and 1.062 inches wide keeping the added footprint compact on the slide or frame. Installation is straightforward: remove the factory rear sight install the mount in the dovetail and secure it with the included set screw where applicable. Because the process is fully reversible owners can swap back to iron sights at any time without altering the firearm. Mounting hardware is included and EGW recommends applying blue Loctite to the mounting screws and torquing them to 15 in/lbs using the required 5/64 inch allen wrench for a secure lasting fit. This attention to installation detail helps ensure the red dot holds zero through recoil and regular use. Compatible with the Ruger 22/45 Mark I Mark II Mark III Mark IV and several Ruger P-series pistols this mount covers a wide range of popular rimfire and centerfire platforms. For shooters looking to add a red dot to a trusted Ruger pistol without permanent modification this mount is a practical well-engineered solution.
