Great magnifier - Holosun HM3X 3x Red Dot Sight Magnifier

I have several guns with Holosun 510C and 512C Green dots, and wanted a great budget magnifier to help with longer ranges. This one fit the bill to a "T". The Glass is clear, and it easily attaches with the quick lock system, it takes some effort to move the magnifier tube into or out of position, which is a good thing. My only ding on it is that it blocks some of the "dot" view in the lower 3-6 o'clock view due to the pivot point.
