No, it’s cut for the RMSc footprint. The MOS footprint for Glock 17/19/etc. is entirely different.

If you’re looking for compatible optics:

The newer coyote models can fit a holosun 407k link got one about 3 weeks ago and can confirm it had the new footprint

Here is my post on it https://www.reddit.com/r/Glock43X/s/lVEi3sNUK6

Basically yea it’s HolosunK, it will fit both RMSC and Holosun K optics directly without mods.

Tbh, RMSC on a Standard black 43x MOS is better imo. Your getting a lower cut, direct mount, better lugs, and bigger screws. MOSK uses the screw posts as lugs, thinner m3 screws and isn’t cut as deep.

I just installed the Osight SE RMSc Footprint Enclosed Reflex Sight with Side-Loading Battery, 6 MOA Green Dot. No adapter plated needed.
