The Trijicon RM33 RMR Mount (SKU AC32004) is a low 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 RM33 keeps the sight as low over the rail as Trijicon's rail mounts go, which suits a rifle with no backup irons in the way, an offset or piggyback position, or any build where you want the sight line close to the bore rather than raised.
How it compares
Need the tall, absolute co-witness height instead? The Trijicon RM34 RMR mount (AC32005) is the other rail option. Browse all red dot sight mounts and rifle scope mounts, every optic on the RMR footprint, or read our co-witness height guide.
Ideal for
- Practical and service rifle setups with no backup irons in the sight line
- Offset and piggyback positions where a low mount keeps the sight close to the rail
- Straight-pull and gallery rifle builds wanting a compact 1× sight
- Airsoft rifle builds fitting an RMR or SRO to a Picatinny rail

Which optics fit the Trijicon RM33 mount?
The Trijicon RM33 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 RM33 fit a standard Picatinny rail?
Yes — the Trijicon RM33 (AC32004) 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 RM33?
No — the RM33 is sold as a mount only, with its mounting hardware.
