Holosun works great! - Holosun OPMOD HS507C-X2 1x Reflex Red Dot Sight

The unit is small and mounted to an aftermarket Glock slide with rmr cut. It can mount directly to the rmr cut on the slide but I wanted a little higher. I converted a trijicon plate adapter by grinding the front off and using a drill to open up the holes and used longer 6-32 screws that had hex holes on the counter sink heads. Screws were 1/2" long from top of head to end of threads. Gently removed a little of the head rim edge with a grinder and used grinder brush wheel to smooth up. Screws were stainless steel from Ace. Manual says 15 in-lbs but for ss Screws I used 10 in-lbs with a tiny amount of blue loktite at end of threads.
