Most Helpful Positive Review RMR Sealing Plate
I had my Glock Slide milled to fit a Trijicon RMR. When mounting the RMR directly to the Glock slide, this mounting plate is necessary because the RMR is wider than the Glock slide. This leaves the battery compartment exposed. The RMR sealing plate closes off the battery compartment as the name of the product indicates. There really isn't much to say about it. It works as intended.

Works as designed

Pretty straightforward, works as designed to seal the battery compartment on the Trij RMR when mounted to narrow slide of my Glock

Trijicon RMR sealing plate

by Christopher Davids, Verified Owner from FL, United States Written on April 16, 2024
Plate fit perfectly on Trijicon RM01 Type 2 when mounted to FN 509c Tactical as well as FN FNX-45. Mount is secure and kept internals dry when used in light rain. Obviously I’m not going to drop my firearm in water to see if it stays dry, but I am confident it will keep out water until it can be picked up and wiped off.

Doesn’t come with screws

by Kpeller, from MA, United States Written on October 3, 2021
Need this plate to seal the optic properly but it doesn’t come with screws even though it was a suggested purchase with the RMR by optics planet. Should have a better description by optics planet. Ordered screws from somewhere else.

Solid sealing plate

by Aspeed, Verified Owner from WI, United States Written on October 2, 2021
Not much to say here, plate does what it’s supposed to do. I’ve called and talked to Trijicon support and they said it’s not always needed (that depends on the mounting situation) but won’t hurt, so I run it with all RMR’s. Why not spend a little bit of money here to protect your RMR and make sure you can keep it running.
Pros:
  • Affordable
Cons:
  • None
Would recommend: Yes

Excellent product

by David, Verified Owner from NM, United States Written on May 7, 2021
I purchased this little plate with the optics bucks I received. It’s a great little product considering all it does is protect the housing from water or any other fluid. It doesn’t raise the sight by any amount that I could tell. The packaging was questionable but at least it still came with a sticker for my collection.
Pros:
  • Waterproof up to 60ish ft
Cons:
  • None
Best Used for:
  • SIGHT
Would recommend: Yes

Make sure you buy it before you melt the site on your firearm

by mef4ud, Verified Owner from FL, United States Written on March 31, 2021
I purchased the plate after having mounted the RMR on my firearm, which required me to re-zero the sight. I have not tested the level of waterproofing the plate adds, but I don’t intend to fire the weapon underwater so it just to prevent rain or other accidental fluids from entering housing.

Needed add on

by Clyde, Verified Owner from GA, United States Written on March 23, 2021
If you are using the trijicon rmr for any kind of serious use I recommend getting this sealing plate. It increases the submersion a good amount while keeping the foot print the same and height almost identical.
Pros:
  • increased submersion
Cons:
  • None
Best Used for:
  • LE,Mil,Defense
Would recommend: Yes
