The new B-Series of optics are the most feature packed optics on the market. While the B-17 retains the the popular 3.2-17x magnification range today’s professionals are asking for, the similarities stop there. These new optics now have locking elevation and windage knobs, zero stop, revolution counter, tool-less elevation zero and a single button illumination control which has been integrated into the parallax adjustment knob. All this and still the same durability, reliability and performance U.S. Optics is known for.

H59: The Horus Vision H59 Reticle is a “field-tuned” version of Horus Vision H58. Horus widened the horizontal grid by one mil for increased wind holdover. And the center cross has been turned into a “broken cross” so groupings are less obscured and more easily seen.
