Rmsc not rmr - Holosun Sub-compact HS507K-X2 1x 2 MOA Dot Red Dot Sights

This is a great sight for the money especially when comparing it to Trijicon's new RMRcc at twice the price. Compact, durable, and great sight picture for a small optic. It's neat to have the dot, circle dot, and circle as options - however I do prefer just using the dot. I am writing this review to warn those who may think its a direct fit for slides cut for an RMR. I've seen some places advertise that it will fit an RMR cut, it will fit the footprint but the 507"K" screw holes do not align the holes in the slide for the RMR. It will fit holes and footprint of an RMSc. I tried this on a Brownells and Trybe slides for a G19 with an RMR cut and it doesn't line up. I was lucky enough to have a G19 Liteslide by Strike Industries that has cuts and holes for different optics, including the RMSc. It lined up and I was able to use the 507K with that slide. 5/5 would recommend this optic
