The EGW Blank Trijicon RMR Sight Mount is a precision-machined aluminum adapter that replaces your pistol's rear dovetail sight, giving you a clean, co-witness platform for mounting a Trijicon RMR or Holosun HS507C red dot. Built from 7075 aluminum with a matte black hardcoat finish, this mount is engineered for shooters who want to run a modern optic on their carry or competition 1911 without permanent modifications—remove it anytime and restore your original sights.
Designed specifically for Baby Desert Eagle (post-2006) and EAA Witness Elite Match platforms, the EGW mount slides into your existing dovetail cut and secures with a set screw. Installation is straightforward: pull the rear sight, install the mount, and bolt your red dot on top. Everything you need ships in the box—two flat-head cap screws (for RMR mounting), one set screw, and clear instructions. The whole assembly measures 1.780" long and 1.1" wide, keeping the footprint compact and balanced on your slide.
Whether you're running a duty gun, building a competition platform, or upgrading a daily carry 1911, the EGW mount eliminates the guesswork of adapting optics to your frame. No gunsmithing, no permanent damage, no excuses. Just solid aluminum, proven hardware, and the flexibility to swap configurations when you need to.

Frequently Asked Questions
What pistols does this Trijicon RMR mount fit?
The EGW mount is confirmed to fit Baby Desert Eagle (post-2006) and EAA Witness Elite Match. It does not fit Rock Island 1911s. If you're unsure whether your gun is compatible, check the dovetail cut at the rear of your slide—the mount uses your existing rear sight dovetail, so any gun with that cut type should work. When in doubt, reach out and confirm before ordering.
Can I remove this mount and put my original sights back?
Yes. The EGW mount is fully reversible. Remove the set screw and mounting screws, slide the mount out of the dovetail, and install your factory rear sight again. No permanent alterations to your frame. This makes it a great option if you want to keep your gun flexible for different roles or missions.
Which red dot sights work with this mount?
The EGW mount is designed for Trijicon RMR and Holosun HS507C. Two flat-head cap screws are provided to secure the RMR to the top of the mount. Confirm your specific optic model before ordering if you're running something else.
What hardware comes in the box?
Two 6-32 flat-head cap screws, one 6-32 × 3/16" set screw, and installation instructions. You'll need a 5/64" Allen wrench to drive the cap screws into the RMR. The instructions recommend using blue Loctite and torquing the red dot mounting screws to 15 inch-pounds.
