The EGW EAA Tanfoglio Witness Trijicon RMR sight mount is a precision dovetail adapter built for shooters who want to run a modern red dot on their Witness platform pistol. If you've got a post-2006 Baby Desert Eagle or EAA Witness Elite Match and you're ready to go optics-ready without permanent modifications, this mount does the job: just remove your factory rear sight, slide the EGW mount into the dovetail, and you're ready to attach your Trijicon RMR red dot. No gunsmithing required, and you can swap back to iron sights anytime.
Built from 7075 aluminum and finished in matte black hardcoat, this mount is engineered to hold zero and take the recoil of centerfire pistol shooting. The low profile design keeps your sight plane intact while giving you the performance benefits of a red dot sight picture. Everything you need for installation comes in the box: two flat-head cap screws (5/64" allen wrench compatible), one set screw, and the mount itself. The included hardware is torqued to 15 in/lbs per EGW's specs, and the system is compatible with Trijicon RMR and Holosun HS507C red dots, giving you flexibility in optic choice.
This is a straightforward solution for Witness owners who want to modernize their sight system without investing in a new slide or sending their gun to a gunsmith. EGW mounts are known for reliable, repeatable performance in the field and at the range, and this one fits the bill whether you're running a defensive setup or a competition gun.

Frequently Asked Questions
Will this mount fit my 1911 or Rock Island pistol?
No. This EGW mount is designed specifically for the dovetail configuration of the EAA Witness Elite Match and post-2006 Baby Desert Eagle. It does not fit Rock Island 1911s or other 1911-pattern pistols. Check your gun's manual or contact us to confirm fitment before ordering.
Do I need to modify my slide or send my gun to a gunsmith?
No modifications required. The mount installs directly into your existing rear sight dovetail. Simply remove your factory rear sight and slide the EGW mount into place. If you ever want to go back to iron sights, you can remove the mount and reinstall your original rear sight.
