The American Defense quick detach Trijicon RMR mount is an excellent option for the popular Trijicon Ruggedized Miniature Reflex sight. This one piece mount, like all American Defense mounts is precision machined from durable 6061-T6 aluminum with a hardcoat anodized finish for long service life.

This mount is designed to place the center of the optic in line with standard AR-15 iron sights for an absolute cowitness.

Featuring ADM's QD Auto Lock Lever system, the AD-MRO can be fully adjusted without tools to accommodate most Picatinny rail systems. This glove friendly locking system ensures the mount will not move until you need to remove it, and provides exceptional return to zero with mounted optics. It is also fully covered by American Defense's lifetime warranty.

American Defense Mini Quick-Release Trijicon RMR M


Great fit. I used it to mount my Trijicon RMR on an MP-15. Now the sight co-witnesses with the front sight post.

RMR Hi-Mount


Great product. Fit perfectly. Works great. One tip for anyone mounting a Trijicon RMR to an AR platform: get the high mount, the low one would be way too low for this sight.

Product Works Perfectly


I bought this mount for a Mossberg AR-15. I was able to get this assembled in minutes and ready to sight in the rifle.

Practical use.


I just installed this mount this past weekend. I sighted it in, and shot 500 rounds with no issues at all. It fit my LMT CQB-16 rail perfectly, its easily adjusted, and even with rapid fire (with safety in mind), it held up perfectly. I'm a very tough guy to please, and rarely give 5 stars for anything, but this mount actually did well. Its tall enough for good line-of-sight, but doesn't get in the way. 5 stars, I would recommend this mount to anyone.

Wow! On time shipping during crazy times.


The order was processed quickly and arrived faster than expected even though most companies aren't even picking up the phone right now. Mount looks solid and is less expensive than the Trijicon mount, but I am going to be waiting several weeks for my rifle to mount it to.



This ADM mount for the Trijicon RMR works perfect, solid mount and co-witness with my irons. The ADM clamping mechanism is the best due to its ability to be adjusted for out of spec rails. Primary Arms of course had it for the best price, in stock, and shipped expediently.



Way easier to use than expected, and no way for it to come loose.

As advertised!


Well built; provides perfect co-witness sighting through my RMR; easily adjusts to fit my flat top rail; quick detach lever is easy to operate; mounting posts and mounting holes mount precisely with RMR unit base; is heavier than the RMR itself but necessary to provide appropriate height for sight; worked flawlessly at gun range and held zero when removed and then remounted.

Nice mount


Great mount. Built well, adjustable tension, positive lockdown, perfect for co witness iron sights.
