This heralded long-range scope has all the hero features that confirm its place in the Premier family of tactical products: Including our Lever-Lock™ system, our first focal plane reticle placement, and our integrated illumination and parallax adjustment knob. Use it on rifles chambered in .338LM and .50 caliber. You get .25 MOA click per hash mark from our Double Turn knobs. There’s even a revolution indicator that provides visual and tactile reference for your position in the travel range. The indicator automatically extends when moving into the second revolution.
