Description
This is EGW's blank version of their popular dovetail sight mount, built for anyone who wants to run a Trijicon RMR or SRO footprint optic on a pistol that never came drilled or milled for a red dot. Instead of being pre-cut for one specific gun, the blank ships oversized so a gunsmith can machine it to match the exact dovetail on your slide. That makes it the go-to piece for odd-ball guns, older models, and builds that fall outside EGW's standard fit list.
The mount is cut from 7075 aluminum and finished in a Type III black hardcoat anodize, so it holds up to the recoil, holster wear, and weather that a carry or range gun sees. It measures 1.780 inches long and 1.1 inches wide, and it carries the full RMR footprint. That means it also accepts optics sharing that pattern, including the Holosun 407C and 507C, plus other red dots that use the same mounting standard.
What Makes the EGW Blank RMR Mount Different
The idea here is simple. You pull the factory rear sight out of the dovetail, drop in the EGW mount, and bolt your red dot on top. The blank gives a gunsmith the material to cut a precise, snug dovetail match rather than forcing a one-size-fits-most part. Because it installs in the existing dovetail, you can pull it back off and return your iron sight whenever you want.
Fitting the Blank Trijicon RMR Sight Mount
This one is not a drop-in. Plan on having a qualified gunsmith machine the dovetail cut so the fit is tight and repeatable. Installation uses the included hardware, a dab of blue thread locker on the mounting screws, and a torque of around 15 inch-pounds. A small piece of paper placed between the optic and the mount during install makes future removal easier and keeps thread locker off the glass.
For anyone with a pistol that sat on the sidelines because nobody made a red dot mount for it, this blank is the workaround that gets it into the optic game.

Frequently Asked Questions
Is the EGW blank Trijicon RMR mount a drop-in part?
No. This is a gunsmith-fit blank, meaning it ships oversized and needs to be machined to match the dovetail on your specific slide. Once a gunsmith cuts it to fit, it installs into the existing dovetail using the included hardware.
Which optics will fit this mount?
It carries the Trijicon RMR and SRO footprint, so any optic built to that pattern will bolt right on. That includes the Holosun 407C and 507C along with other red dots that share the same RMR mounting standard.
Can I put my iron sight back on later?
Yes. Since the mount installs in the dovetail where your rear sight sat, you can remove it and reinstall your original rear sight whenever you like. Just keep in mind the dovetail will have been machined to fit this mount.
What hardware comes with the blank RMR mount?
The mount ships with two 6-32 flat head mounting screws and a 6-32 set screw. EGW recommends blue thread locker on the mounting screws and torquing them to around 15 inch-pounds for a secure hold.
