The Trijicon RMR Mount with Bosses for 3.5x, 4x, and 5.5x ACOG Models gives you a proven way to add a red dot sight to your existing combat optic. If you're running one of Trijicon's compact ACOG rifles scopes and want the speed and simplicity of a co-witnessed red dot, this mount delivers. It's built around Trijicon's standard boss interface, so it integrates seamlessly with compatible ACOG variants without modification. Whether you're setting up a patrol rifle, home defense carbine, or precision-focused duty gun, this mount lets you layer two sighting systems on the same rail real estate.
The install is straightforward: the mount clamps to the ACOG using the included hardware, and your RMR slides on top with its own fasteners. You get a solid, repeatable platform that lets your red dot sit just above the scope's magnified image. Most operators prefer this stacked setup for the flexibility—you can run the dot solo at low magnification for close work, or use the scope for precision shots while the dot sits ready as a backup. The Trijicon ecosystem is known for holding zero under abuse, and this mount respects that standard.
This is the genuine Trijicon mount with bosses—the critical piece that bridges your ACOG and RMR. Make sure your ACOG model matches one of the compatible magnifications before ordering: the 3.5x, 4x, and 5.5x lines are the supported platforms. Older or newer variants may use different mounting schemes, so verify your scope version first.
| Compatibility | Trijicon 3.5x, 4x, 5.5x ACOG |
| Mount Type | Boss-interface |
| Included Hardware | Mount, mounting screws, RMR screw |
| Manufacturer | Trijicon |
Yes, if your ACOG is a 3.5x, 4x, or 5.5x model with a boss interface. Verify your specific ACOG magnification and variant before purchasing, as other models may require different mounts.
This mount is designed for the Trijicon RMR red dot. Confirm your RMR model is compatible with RMR-pattern mounting.
The mount ships with the bracket itself, the mounting screws that secure it to your ACOG, and the RMR attachment screw needed to secure your red dot to the mount.
This dual-optic stack is common in tactical and duty setups. Whether it suits your hunting or competition discipline depends on your zero distance, shooting style, and magnification needs—consult your ACOG and RMR manuals for proper co-witnessing and alignment.
