Fantastic Optic and Amazon service.
I was able to pre order this optic knowing that even if I were to wait around until it came back in stock that it would be fulfilled by the preorders. I called on the couple of occasions in to inquire if they had an ETA they assured me that it would be towards the end of the year, and actually shipped it out the same day they received shipment. Big 5 star to them for their service. On to the optic it self. This small little dot is quite the new development and the future of affordable red dot optics. Which by far Holosun wins hands down on all the other brands with their unique dot/ring design. Over all I am happy how this optic turned out.

Terrific experience
I contacted them a couple of times about my backordered red dot site. They quickly got the info I requested and got back to me right away. The info was accurate and I got the site on time. Couldn’t ask for a better experience.
