It works exactly as described! - Holosun Sub-compact HS507K-X2 1x 2 MOA Dot Red Dot Sights

I bolted it down to my sig X macro without any kind of plate straight to the slide torqued it down and held zero. As a former military member. I really wanted to go with trijicon or eotech. But at the time I just didn't have the money This is definitely not made in the usa style red dot butt I'll take it. It just works and I love the shake awake!
