Love it as much as my eotech g33 magnifier! - Holosun HM3X 3x Red Dot Sight Magnifier

I bought this as a cheaper alternative to another eotech and I have to say that it is just as good if not better. The spring to slide it out of the way is just as crisp and tight as the eotech. Eye relief is magnificent and clarity of glass is superb. my only gripe is that you need a screwdriver or multitool to adjust it. the thing it comes with is worthless and too small. and the slots in the adjustment knobs are too slim for a bullet casing.
