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.

Gen II XR: The Gen II XR reticle in the B-17 features hold over points below zero to better facilitate range estimation and trajectory compensation. The reticle incorporates alternating hash marks and dots that are spaced out in ½ MIL increments. The hash marks and dots represent 5 MILs of total elevation adjustment above the horizontal axis; 10 MILs of elevation adjustment below horizontal axis and 5 MILs of windage adjustment to the left and right of the vertical axis. The Gen II XR reticle is thinner to obscure less of the target for a cleaner image.
