  • Looks and fits great!
Exactly as described and works great. It was missing the built in elevation and windage adjustment key but I contacted Holosun after registering it, and they sent me the part to replace.

  • Magnifier
The eye relief is not the best however if your Red/green dot is zeroed at25yards then you go to use the magnifier it’s good at a 100 yards dead on..

  • Great magnifier but too pricey
Great magnifier but the price is too much. I can get a scope with a 4-15 magnifier for that price. The damn thing is the price of a scope.
