The new B -Series of optics are the most feature packed optics on the market. While the B-10 retains the the popular 1.8-10x 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: Designed in conjunction with George from GA Precision, this MIL based reticle offers full MIL as well as ½MIL increments. A total of 9 MIL’s from the center down on the vertical axis, and 4 MIL’s left and right of center on the horizontal axis.
