The Trijicon 3x25 MRO HD Magnifier with flip-to-side mount is a compact 3-power magnification optic built to extend your effective range when paired with the MRO HD red dot. If you're running a red dot on your rifle but want the precision to reach out farther—whether you're hunting, competing, or training—this magnifier fills that gap without adding bulk or eating up valuable rail space. The flip-to-side design means you can swing it out of the way instantly, giving you the speed of a dot for close work and magnified accuracy when you need it.

Build is pure Trijicon: a solid aluminum body rated to 33 feet submersion keeps things durable in the field. The magnifier uses an adjustable diopter (–2.5 to +2) so you can dial the image sharp to your eyes, and toolless turrets let you center the field of view in minutes. The quick-release levered mount isn't proprietary theater—it's designed to clear standard backup iron sights and works with either 1/3-cowitness or full-cowitness MRO HD mounts thanks to included riser plates and fasteners. At 6.5 ounces and just under 3 inches long, it won't throw off your balance or handling.

One thing to know upfront: the MRO HD Magnifier uses Trijicon's own footprint, so it pairs only with Trijicon's magnifier mount (included here). That's not a limitation—it's how Trijicon maintains the fit and optical alignment. If you're already committed to the MRO HD ecosystem or building around it, this magnifier is the natural next step.

Frequently Asked Questions

Will this magnifier work with red dots other than the MRO HD?

No. The MRO HD Magnifier is designed specifically for Trijicon's MRO HD red dot and uses Trijicon's proprietary mount footprint. It will only pair with the Trijicon magnifier mount system that's included.

Can I use this magnifier with backup iron sights?

Yes. The flip-to-side mount is designed to clear standard backup iron sights when flipped to the side, so you can keep your BUIS in place and deploy the magnifier only when needed.
