This is the optics adapter plate for the newly released GLOCK 43X MOS and 48 MOS with RMSc Optic Cut.

This plate is required to mount a Holosun 507k / 407k without having to modify the existing recoil posts on the slide.

The plate is .045″ thick.  It’s CNC machined from 6061 and Type III black hard anodized.
