The Trijicon RMR RM34 Picatinny-style rail mount gives you a rock-solid platform for mounting a Trijicon RMR red dot sight to any rifle with a Picatinny rail. Built from lightweight aluminum, this mount is engineered to keep your optic secure and repeatable shot after shot—whether you're running it as a primary sight or stacking it behind a magnified optic for rapid close-range transitions. The RM34 uses a full-length locking bar and grooved thumbscrew that lock down fast and won't creep under recoil.

This mount sits at an elevation that lets you position your RMR behind a scope or magnified sight, so you can rotate slightly and transition to the dot for targets inside 25 yards without removing your primary glass. That speed matters when hunting or training. The matte black finish is durable, low-profile, and blends into any tactical or hunting setup.

If you're already running Trijicon glass and want the speed of a red dot without committing to a new rifle or sacrificing your magnified zero, the RM34 is the straightforward way to get there. Installation is straightforward—bolt it to any Picatinny rail, lock it down with the thumbscrew, and go.

Frequently Asked Questions

Can I use the RM34 behind a rifle scope or magnified optic?

Yes. The RM34 is designed with extra elevation so you can mount your RMR behind a primary optic and quickly transition to the dot sight for close-range shooting by rotating your rifle slightly.

What rails does this mount fit?

The RM34 uses Picatinny-style (MIL-STD-1913) mounting, so it fits any rifle rail that follows that standard—AR-15 upper receivers, AK mounts with Picatinny adapters, and most modern tactical rifles.

How secure is the thumbscrew attachment?

The full-length locking bar and grooved thumbscrew lock down tight enough to handle rifle recoil and maintain repeatability. The grooved design makes it easy to tighten or loosen by hand without tools.

What comes in the box?

This is the mount only. You'll need a compatible Trijicon RMR red dot sight to complete the setup.
