Accessories for Ruger Mark I

The Mark I is the earliest pistol in Ruger's Mark series of .22 LR rimfire pistols, the line that runs through the Mark II, Mark III and Mark IV. Our parts for it all use the rear sight dovetail.

Red dot mounts

EGW makes two aluminium mounts that replace the rear sight: one cut for the Trijicon RMR footprint, one for the smaller Shield RMSc, Leupold DPP and Holosun K-series pattern. No milling is needed, and the change can be undone.

Adjustable rear sight

Windage and elevation are both adjustable on LPA's steel rear, handy for re-zeroing after switching ammunition. It comes with a blank grooved blade, white dots or white lines.
