Most Helpful Positive Review Need it for Glock mos
This product functions perfectly. My only complaints is trigicon and Glock both do not make it apparent that this part is 100% necessary to mount the rmr to a Glock mos plate. If you don't use this the provided screws are just a tiny bit to long and won't tighten down all the way.
Most Helpful Negative Review Waste of money
Don't waste your money buying this. A countersink 6-32 bolt 3/8" long from the hardware store will do the same thing. Shame to Glock and Trijicon for this kit. This kit is a proprietary length bolt and a shim that only accomplish the same as a trip to Home Depot and some change.........................

This completed my installation of the Trijicon RMR red dot sight. It’s official Trijicon product and I’m pleased with it.

Not the right mount

by ILL Will, from GA, United States Written on January 7, 2024
Certainly somebody has replaced the mount with something that is not the right mount. Came dirty and smelling of burnt carbon. I think somebody did the old switcharooney or this is definitely a quality control issue will verify the rest of my order and hope this is not an ongoing standard when it arrives. The reviews had me scared but I said let me see for myself.

Reliable plate sealer

by 22 Tactical, Verified Owner from IL, United States Written on October 28, 2023
Perfect addition to the RMR. Fits my G34 MOS and will retain well. A shame this unit doesn't come with a universal plate to hold the battery in, but its reliability is a fair trade off. Well worth the $15.
Pros:
  • Easy to install
Cons:
  • None
Best Used for:
  • Home Defense

Plate for RMR

by MM, from MN, United States Written on March 21, 2023
Would have been a 5 star, the product is a must. Upon opening the package I realized it was warped and would not sit flush to the red dot. I tried to bend it flat, but it did not fix it. I found another plate and that worked fine.
Would recommend: No

Functions as described

by jtyra2002, from TX, United States Written on June 5, 2022
This product consists of a thin sheet of metal that fits between the bottom of the RMR and the top of the pistol slide, plus two screws. It fits as it should and also seems to prevent water intrusion into the RMR’s battery compartment.
Pros:
  • Simple & easy installation, no drilling
Cons:
  • Thin

by Dave H., Verified Owner from KS, United States Written on February 14, 2022
The Trijicon RMR Mounting Kit for Glock MOS is a must have for mounting the Trijicon RMR Type 2 Adjustable LED 3.25 MOA Red Dot Sight.

Pros:
  • Fit

Cons:
  • None
Best Used for:
  • Glock MOS Pistols

RMR mounting plate.

by Nate, from AL, United States Written on October 28, 2021
Works great! Put this on a Glock 34 MOS Gen 5, solid lockup, no flickering on the RM06. This is a must have for anyone using the MOS system on glocks. I’ll hopefully be buying a few more of these in the future, need to finish a few current builds first.
