Straightforward, simple and effective - VISM Ruger PC Carbine RMR Footprint and Rear Sight Mount

This mount is as basic and simple as can be. That said, it works perfectly. The Ruger PC has a rail for scope mounting, but it isn’t on the barrel. This makes repeatability an issue. This mount attaches directly to the barrel and allows for co-witness of the iron sights. This is excellent and enhances the platform significantly.
