TruGlo TGTG8950C2 Pistol Red Dot Sight Mount Black Nitride Fortress

Mount any red dot sight to your pistol without having to match the slide. On Glock, M&P, and CZ models, the mount replaces the rear sight, turning a standard sight dovetail into an optic mount. On the Ruger Mk series models, the mount replaces the Picatinny rail on the slide, allowing you to mount the optic lower without the use of a Picatinny adapter.
