Glock, Holosun 407k/507k, Optic Milling

This will mill your Glock slide for the Holosun 507K red dot, without any adapter plates. The red dot is small enough to fit in front of the rear factory dovetail, and we can mill it deep enough to just see your factory height sights through the red dot.. The base of the red dot is .116" above the top of the slide, so any sights higher than that will be visible. This will drill/tap the holes for the M4-0.7 screws which come with your red dot, which may require shortening to fit.
