If you've got a 1911 or 2011 wearing a Bomar-style rear sight and you've been eyeing a red dot, this EGW mount is one of the simplest ways to get there. It slips right into your existing rear dovetail, so there's no slide milling, no gunsmith trip, and no permanent changes to the gun. Machined from 7075 aluminum and finished in a matte black Type III hardcoat anodizing, it's built to hold zero and take a beating.
Installation is about as painless as it gets. You pull the factory rear sight out of the dovetail, press this mount into place, and bolt your optic down with the included hardware. The two 6-32 flat head screws are the ones you'll use for a Trijicon RMR, and they call for a 5/64 inch allen wrench. EGW recommends a dab of blue Loctite and torquing the mounting screws to around 15 in/lbs. Worth noting that this is a press-fit mount, so a sight pusher tool can make the job a lot easier if your dovetail is tight.
The mount carries a Trijicon RMR footprint, which also accepts the Trijicon SRO along with Holosun 407c, 507c, and 508T optics that share that pattern. It measures 1.780 inches long by 1.1 inches wide and is a true one-piece base, so there's no stacking of plates or adapters. Keep in mind this version is built for Bomar sight cuts specifically, and it will not work with optics-ready slides or the smaller RMRcc.
This mount is designed around the Bomar rear sight cut, which shows up on a lot of match and custom pistols. Think STI/Staccato Edge, Les Baer 1911s with adjustable rears, and Colt Gold Cup Trophy models running a Bomar rear, among others. The nice part is that it's completely reversible. If you ever want your iron sights back, you pull the mount and drop your original rear sight back in the dovetail.
This mount is cut for the Bomar-style rear sight dovetail found on a range of match and custom pistols. That includes guns like the STI/Staccato Edge, Les Baer 1911s with adjustable rear sights, and Colt Gold Cup Trophy models with a Bomar rear, among others. It will not work with optics-ready slides, so make sure your pistol has a Bomar rear sight cut before ordering.
The base uses a Trijicon RMR footprint, so it directly accepts the Trijicon RMR and SRO. Holosun optics that share that pattern, like the 407c, 507c, and 508T, will also bolt right on. It is not compatible with the smaller RMRcc, which uses a different footprint.
No machining or permanent modification is required. You remove the factory rear sight, press the mount into the dovetail, and secure your optic with the included 6-32 flat head screws using a 5/64 inch allen wrench. Since it is a press-fit mount, a sight pusher tool can make the install smoother, and a touch of blue Loctite with roughly 15 in/lbs of torque on the screws is recommended.
Yes. The mount is fully reversible, so you can pull it out of the dovetail and drop your original rear sight back in whenever you like. Nothing about the installation permanently alters your pistol.
