Nightforce NXS rifle scopes are one of the toughest rifle scopes from the company Nightforce. These rifle scopes are also the predecessors of the newer ATACR series. Also the NXS rifle scopes are widely used in the military, police, and law enforcement. The housing of these rifle scopes is very rugged, because Nightforce designed this series specifically for the use of military personnel.
The smaller magnification models, NXS 1-4x24 and NXS 2.5-10x42 are meant also for hunting use, especially because of the compact size and low weight. These models have also capped turrets, which others don't. All other scopes from this series have exposed tactical turrets for quick elevation and windage adjustment. These turrets can be either in MIL with 0.1 mrad of adjustment, or in MOA, with ¼ MOA of adjustment per click. Normally these turrets have no ZeroStop, but you can order this accessory optionaly. With this accessory, the turret stops at zero and it won't go further down, so it is easier to use at low light.
The eyepiece is adjustable for different diopters, and when you set the correct setting, there is a counter ring to fix this setting. Since this is set, there's no need to adjust it anymore. The reticle in all NXS rifle scopes is set in the second focal plane, so the reticle doesn't cover a lot of the target at bigger magnifications. In this series, you can choose if you want an illuminated or a non-illuminated reticle. If you decide to use the illuminated version of the scope, the illumination control is on the left side of the rifle scope (when looking from the eyepiece). To adjust the brightness, the cap has to be taken off, and then with a screwdriver, you adjust the desired illumination. On this turret, there is also the parallax adjustment on the scopes with bigger magnifications.
The lenses used in the NXS rifle scopes are fully multi-coated for more light transmission, better contrast, and more clarity. The housing is made from a single piece aircraft-grade aluminum, are totally waterproof and filled with dry nitrogen to prevent internal fogging at low temperatures. These rifle scopes are built to withstand even the strongest recoiling calibers like the .50 BMG, and the clamping diameter on all models is 30 mm.
The warranty on this products is 30 years.
The Nightforce NXS rifle scopes can only be mounted with 30 mm rings.
