The EGW Trijicon RMR to Holosun 407/507C Picatinny Rail Adapter (brand part no. 49600) lets shooters mount an RMR-footprint red dot onto any standard Picatinny rail without cutting a new dovetail or drilling a slide. Built by Evolution Gun Works, a longtime name in precision mounting solutions, this adapter is machined to accept both Trijicon RMR and Holosun 407C/507C footprint optics interchangeably. It’s a practical upgrade for shooters who want to move a favorite red dot between a rifle rail and a co-witnessed mounting setup without buying a second optic. The compact footprint keeps the sight low and close to the bore for a fast, natural sight picture.
