We have redesigned our RMR / Holosun to MOS adapter plate once again.


Made from 6061 Aluminum

Fills those ugly sight gaps in front and behind your Red Dot

Four locating pins / lugs

Thinner design, Lighter Design, more than Twice the Thread Engagement to secure your red dot to the plate.

The screw sizes are machined into the plate in case you need more, you’ll know the size and length!

Comes with M3 screws to secure the plate to your pistol as well as 4-40 screws to secure your RMR to the plate.

The C&H Adapter Plate allows you to mount your Trijjicon RMR or your Holosun 507 Reflex Sight to your GLOCK MOS slide perfectly.

There will be no more gap, everything looks nice and neat on your Glock MOS. Comes with two screws.

This adapter plate does not include the Trijjicon RMR or the Holosun Reflex sight.
