Details
Description
Trijicon RM33 Mount (AC32004) moves an RMR or SRO off a pistol slide and onto a rifle, carbine or PCC rail. It is the low one of the pair: machined aluminium, clamped to Picatinny, sitting the optic close to the rail rather than up at co-witness height.
How It Compares
Fitting to an optics-ready pistol instead calls for the RMR pistol mounting kit. If you need the dot up at iron-sight height, that is the RM34 tall mount. There are more red dot sight mounts and the wider Trijicon range to look through.
Ideal For
- Putting an RMR or SRO on a rifle or carbine
- PCC and other rail-mounted builds
- Any optic on the RMR or SRO footprint
- Shooters who want the dot low over the rail

Product FAQs
Which optics fit the Trijicon RM33 mount?
The Trijicon RM33 takes any optic on the Trijicon RMR or SRO footprint. It is worth confirming your sight's footprint before ordering.
What is the difference between the RM33 and the RM34?
The difference is height, as the RM33 is the low mount and the RM34 raises the optic for co-witnessing. The RM33 sits the sight close to the rail rather than up at iron-sight height.
What is the Trijicon RM33 made from?
The Trijicon RM33 is machined aluminium. It clamps directly to a Picatinny rail.
What rail does the AC32004 fit?
The Trijicon RM33 clamps to a Picatinny rail. That covers rifles, carbines and PCC builds with a Picatinny top rail.
What is the RM33 mount actually for?
The Trijicon RM33 moves an RMR or SRO off a pistol slide and onto a rifle, carbine or PCC rail. It is the low mount of the RM33 and RM34 pair.
What comes with the Trijicon RM33 AC32004?
The package contains the Trijicon RM33 Picatinny mount and its mounting hardware.
Can I use the RM33 on an optics-ready pistol?
No, the RM33 is a Picatinny rail mount rather than a pistol slide adapter. Fitting an RMR to an optics-ready pistol instead calls for the Trijicon RMR pistol mounting kit.
How quickly will the Trijicon RM33 arrive in the UK?
Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival, and checkout is secured by Shopify.
