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.

MIL Scale GAP: The MIL Scale GAP Reticle in the B-17 features full MIL and ½ MIL hash marks that are laid out in a clean display. The full MIL hash marks are numbered every 2 MILs for quick and easy reference. The hash marks represent a total of 9 MILs of adjustment below the horizontal axis; 4 MILs of adjustment above the horizontal axis and 4 MILs of adjustment to the left and right of the vertical axis.
