Big County's Review of Primary Arms Holosun HE509-RD Enclosed Solar Powered Red Dot Reflex Sight

Put this holosun 509rd on a smith and wesson m&p 2.0 10mm carry comp and I have put 800 plus rounds through it and it has held up nice so far. It has stayed tight and zeroed. I really like this red dot. The only thing I don't like is i can't use my open sights now I don't know if I can get different sites to cowittness at this time.
