The EGW Kimber Fixed Rear Trijicon RMR Sight is a precision dovetail mount that lets you swap your factory rear sight for a modern red dot optic without permanent modifications. Built from 7075 aluminum and finished in matte black, this mount is designed specifically for Kimber pistols and fits Baby Desert Eagle (post-2006) and EAA Witness Elite Match platforms. It's a clean, reversible way to co-witness or replace your iron sights with a Trijicon RMR or Holosun HS507C red dot—and you can take it off and reinstall your original rear sight anytime.
Installation is straightforward: remove your factory rear sight, slide the EGW mount into the dovetail, and secure it with the included hardware. The mount comes with two flat-head cap screws (requiring a 5/64" allen wrench) and a set screw for final tightening. The whole process is tool-simple and requires no gunsmithing or permanent alterations to your slide. Because this is a direct dovetail replacement, you're not adding height or changing the ergonomics of your carry gun—just swapping one rear sight assembly for another.
If you're upgrading to a red dot for faster target acquisition or low-light shooting, or if you want the speed of a modern optic without the cost of a slide-milled pistol, this is a practical, affordable solution. The aluminum construction is lightweight and durable, and the matte black finish resists glare and blends with most tactical setups. Installation instructions and all hardware are included.
