Optic Cut Cover Plate - Trijicon RMR / Holosun "C" Series - Black Anodized Aluminum

(36 reviews) Write a Review

This aluminum cover plate fills the optic cut void in the slide when not using a Trijicon RMR.

Precision machined from 6061 Aluminum, this plate is .160" thick and is designed to work with Trijicon RMR pattern Optic Cut pockets that are .160" deep. This plate features relief cuts on the bottom surface for use with Optic Cut pockets that feature locating bosses.

These cover plates will be Anodized Black only.

If you are purchasing a cover plate in conjuction with Black or Stonewash Nitride refinishing for your slide, you will receive a black anodized plate. Aluminum cover plates cannot be Stonewashed.


Includes two 6-32x1/4" mounting screws.

These plates are only available for the Trijicon RMR Optic Cut on the following models: 17/19/26/22/23/27/31/32/33/29/30. While they will fit wider optic cut slides (20/21/29/30/etc) the edges will not be flush.

*While this plate is likely to be compatible with other manufacture's RMR optic cuts, we only guarantee compatibility with our Optic Cut. NOT COMPATIBLE WITH BROWNELLS RMR CUT SLIDES.

    Well constructed, and fits perfectly. Well worth adding this to your purchase, especially if you don't always want an optic on your handgun.

    Very nice fit and finish. This is a must if you want to carry your pistol without a red dot installed. Good price too.

    Fit & finish are perfect! Super snug which only required gentle tap into the RMR cutout. Blends right in. I'm more than satisfied!

    Bought this plate for an aftermarket Glock compatible slide. It specifically says Maple Leaf compatibility but I opted to try to fit it to my slide. It fits the RMR cut so I am satisfied.

    Great cover plate. It fits Maple Leaf's RMR cut perfectly, and looks good too. Very happy with it.
