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.

IGR: Designed by U.S. Optics’ GM, this MOA based reticle offers 1 MOA out to 10 MOA marks. The open center features a red dot in order to provide a clear view of the shooter’s groupings, while the fine cross hairs present a clear and crisp image without obscuring the target. The IGR provides 30 MOA on upper and 60 MOA on lower vertical axis, while providing 30 MOA left and right on horizontal axis.
