The NX8 2.5-20x50 builds upon the rugged, reliable, and repeatable legacy our NXS line built over more than 20 years. Despite the compact size, the NX8 F2 riflescopes feature Nightforce's ZeroStop turret, DigIllum reticle illumination, power throw lever, and several new purpose-built F2 reticles. The optical system uses ED lenses to allow for great optical quality in a system with an 8x zoom ratio and short overall length. The new MOAR-CF2 and MIL-CF2 reticles are calibrated at 20x and provide users with an open center with dot and intuitive numbering of subtensions for a clear view of the target and fast holds anywhere in the reticle. For hunters or shooters who prefer a reticle in the second focal plane that stays consistent in size throughout the magnification range, the Nightforce NX8 F2 scopes will take your capabilities to a whole new level.
