Details
Description
Trijicon RM66 Mount (AC32029) puts an RMR or SRO on top of an ACOG, so a close target no longer means shooting through magnification. It bolts to the top M1913 rail on Trijicon 4x32 LED-illuminated ACOG models (TA02 and TA110) — a plain aluminium adapter with nothing to adjust, which is what you want between two optics that both need to hold zero.
How It Compares
If the dot is going on a flat rail rather than an ACOG, look at the red dot sight mounts. The optics themselves are in the Trijicon range, and fitment questions are covered in our footprints explainer.
Ideal For
- ACOG users who want a close-range dot above the glass
- Trijicon 4x32 LED-illuminated ACOG models (TA02 and TA110)
- Optics on the RMR or SRO footprint
- Switching between magnified and 1x without changing optics

Product FAQs
Will the Trijicon RM66 fit my ACOG?
The RM66 fits Trijicon 4x32 LED-illuminated ACOG models (TA02 and TA110). Check your ACOG model, and check that your dot uses the RMR footprint.
Do I lose my ACOG zero when fitting the RM66?
No, the RM66 adapter bolts to the rail on the ACOG rather than to anything on the rifle, so the ACOG itself stays where it is. There is nothing on the adapter to adjust.
Which red dots can I mount on the Trijicon RM66?
The RM66 takes any optic cut for the Trijicon RMR or SRO footprint. That includes RMR-footprint sights and the SRO.
What is the point of the RM66 AC32029?
The Trijicon RM66 puts an RMR or SRO on top of an ACOG so a close target no longer means shooting through magnification. It lets you switch between magnified and 1x without changing optics.
What is the Trijicon RM66 made from?
The Trijicon RM66 is a plain aluminium adapter. Its mounting hardware is supplied with it.
What comes with the Trijicon RM66?
The package contains the Trijicon RM66 ACOG mount and its mounting hardware.
How does the RM66 differ from a rail mount?
The RM66 bolts to the top rail of a Trijicon 4x32 LED-illuminated ACOG (TA02 and TA110) rather than clamping to a rail on the rifle. If the dot is going on a Picatinny rail instead, a rail-type red dot mount is the right choice.
When will my Trijicon RM66 arrive?
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.
