I just mounted a new Vortex Strikefire on my CZ 858 and think that this is one of the best red dot scopes for the money. The red dot is quite crisp is bright enough that I only used the lowest two settings on a very sunny day. Took about 20-30 rounds to zero at 100 yrd.
This scope feels very very solid, optics are clear and looks awesome to boot. Perhaps the only downside is the 2x magnifier, which seems pretty cheap and will probably never see the light of day on my rifle again. Overall, highly recommended.
