Nice little Aimpoint clone
I hope I didn’t offend Holosun with my headline, because I think they’re doing amazing things. Of all the budget options I’ve tried, Holosun continues to be my favorite red dot sight. I have lots of trigger time behind Aimpoint PRO’s and the only real advantage the Aimpoint gets over the Holosun is the larger field of view due to its larger tube, and the battle proven name. One day when Holosun wins a military contract, the market will get very interesting.

Great sight at this price. Equal to those much more expensive.
This red dot works as advertised. Holds zero nicely, battery lasts almost forever. No problems whatsoever.
