The Trijicon RM34 RMR Mount (SKU AC32005) is a tall Picatinny rail mount in machined aluminium that carries any Trijicon RMR or SRO red dot sight — anything on the RMR footprint — on a rifle, carbine or shotgun rail.
The RM34 sets the sight high enough for an absolute co-witness, so an AR-pattern front and rear iron sight appear in the middle of the window with the dot sitting on the same point of aim. That is the height to choose if you want the irons usable through the optic rather than tucked below it.
How It Compares
Need the low height instead? The Trijicon RM33 RMR mount (AC32004) is the other rail option. Mounting on top of an ACOG rather than a rail? The RM35 (AC32007) and RM66 (AC32029) piggyback an RMR on ACOG models that carry mounting bosses. Want the optic and mount as one purchase? See the RMR Type 2 3.25 MOA red dot sight with the RM34 mount. Browse all red dot sight mounts and rifle scope mounts, every optic on the RMR footprint, or read our co-witness height guide.

Frequently Asked Questions
Which optics fit the Trijicon RM34 mount?
The Trijicon RM34 carries Trijicon RMR and SRO red dot sights, and any other sight built on the RMR footprint. The optic is not included with the mount.
What is the difference between the Trijicon RM33 and RM34 mounts?
The RM33 (AC32004) is the low-profile Picatinny mount and the RM34 (AC32005) is the tall one, which raises an RMR or SRO to an absolute co-witness with AR-pattern iron sights. Both fit standard Picatinny rail and take the same RMR-footprint optics.
Does the Trijicon RM34 fit a standard Picatinny rail?
Yes — the Trijicon RM34 (AC32005) clamps to standard Picatinny rail, which covers AR-pattern flat-tops and most modern rifle, carbine and shotgun receivers and handguards.
Is the optic included with the Trijicon RM34?
No — the RM34 is sold as a mount only, with its mounting hardware. If you want both together, we stock the RMR Type 2 3.25 MOA red dot sight supplied with the RM34 mount.
