Nightforce B.E.A.S.T. (Best Example of Advanced Scope Technology) rifle scopes are the flagship tactical rifle scopes from this company, and have all the newest technologies inside Nightforce is capable of. Like the Nightforce ATACR scopes, also these models are widely used in the military, police and law enforcement. This means, these rifle scopes have to withstand most any abuse, and have to be capable of handling even the strongest calibers like the .50 BMG.
The totally new design from Nightforce stands out from other scopes, and these scopes have also new features no other scopes have. One of these features is the elevation turret, which doesn't have 0.1 MIL or ¼ MOA adjustment per click, but the spacing is bigger with 0.2 MIL or ½ MOA per klick. But, if you need a more precise adjustment, there is a small lever under the turret, which adds half a click. Because of this new feature, you get 20 MIL or 60 MOA elevation per turn. This newly designed turret has also a locking mechanism, which is located on the top of the turret. You simply turn the knob on the top, and it pops out. You see also a red line under this top, which means the turret is locked in place. The turret has also a zero stop function, so you can't go under the zero adjustment. This is also very helpful if you use the scope in low light and don't see the numbers on the turret.
Also the windage turret is new designed, which has a locking mechanism on the zero. To adjust the windage, you have to press a red knob, and then turn in to the desired value. This turrets clicks are different, with normal 0.1 MIL or ¼ MOA of adjustment.
Optically Nightforce has taken the best ED – Low dispersion glass, for best possible light transmission, optical clarity, and contrast of the picture. These lenses are additionally fully multi-coated, to improve all these properties. The reticle is set in the first focal plane (reticle size changes with magnification) what makes this scope a true tactical MIL/MIL rifle scope. The reticle can be with or without illumination, depending on the reticle. Nightforces reticles are illuminated and Horus reticles aren't. The illumination is similar to the Nightforce ATACR rifle scopes, which is adjustable with just pushing the button on the parallax adjustment turret. Also here you have 5 red and 5 green colored illumination brightness levels. This new illumination is called Nightforce Digillum. The parallax turret is adjustable from 45 yards (41 meters) to infinity.
The eyepiece is very similar to the ATACR rifle scopes, on which is a counter ring to fix the diopter setting. When you make your setting, the entire eyepiece is rotating when changing the magnification. On the B.E.A.S.T. rifle scopes, you get from minimal to maximal magnification in just 180-degree turn.
The entire housing is made from a single piece aircraft-grade aluminum, to increase the toughness of these rifles scopes. The clamping diameter is 34 mm, so many rings or monoblock mounts are available. This housing is also filled with dry nitrogen to prevent internal fogging at low temperatures, and is completely O-ring sealed to be waterproof even if accidentally submerged under water.
With the rifle scope itself, you get heavy duty Tenebraex flip up covers that are specifically made for Nightforce. In the box you also get a small throw lever for easier adjustment of the magnification. The warranty on these rifle scopes is 30 years, what is really a lot for tactical rifle scopes that are used in harsh environment.
The Nightforce B.E.A.S.T. rifle scopes can only be mounted with 34 mm rings.
