Product review (5 stars): Works nicely for Hi Point 995
Installed it with 1/2 inch UTG compact 3 slot riser on Hi Point 995 for 1/3 lower co-witness with the iron sights. Had to raise front and rear sights slightly for best co witness since the red dot sight mounts low on the rail, even with the riser  The red dot is precise and the adjustments work well. The dot is smaller so you can have increased accuracy vs the cheaper 5 MOA red dots. It holds zero and the only issue I had was that I had to screw the battery cover on tighter since it can loosen up when you turn the brightness dial. The image thru the glass is nice and clear using the irons too.
