"Nightforce Optics manufactures precision riflescopes, constructed with rugged housings and robust mechanics to take a beating and continue preforming in real-world combat environments. The NXS Rifle Scope has a 30mm main tube to provide an incredible 100 MOA of elevation adjustment and 60 MOA windage adjustment. A high speed ZeroStop elevation turret lets you dial up for long range shots, and then return to your original zero without having to see your dial. The side parallax adjustment knob is marked with approximate numbered distances. An integrated Power Throw Lever (PTL) makes diopter adjustments fast and positive, and the diopter can also be locked to ""set and forget"". Fully multi-coated ED glass results high light transmission values, brilliant images from edge to edge, and exceptional color contrast. The NXS Rifle Scope comes in several second focal plane reticles calibrated for long range shooting.
