Ergonomics of Nightforce ATACR 5-25×56 tactical riflescope is quite similar to that of classic Nightforce NXS. The visible difference is in the size as this ATACR model is 0.6 inch shorter than the NXS one. ATACR 5-25×56 weighs 38.7 ounces. In fact, compared to other scopes, one third of the scopes were heavier than this. Just take the example of scopes belonging to Schmidt and Bender, they are found to be just 1 ounce heavier than this. Now, coming to the eye relief, we see that it is consistent throughout the magnification range.
Ergonomics of Nightforce ATACR 5-25×56 scope includes the ocular bell for magnification that rotates the entire round for adjusting magnification. One of the basic advantage of the ocular bell’s design at ATACR 5-25×56 is the ability of the shooter to adjust magnification from behind the riflescope without requiring to lift his or her head.
However, this means you will not get common flip-up scope covers that you find in the ones made by Butler Creek. This is not present in the ATACR because if you rotate the entire magnification with the flip-up scope’s cover open, the same will hit the rifle and consequently break. To avoid any such breakage of the cover, you can opt for Butler Creek Tactical One Piece Flip Caps that are made up of rubber instead of plastic, which helps you avoid any kind of breakage.
One of the drawbacks here is that you will not be able to see what rotation you are on. The revolution indicator on Nightforce ATACR 5-25×56 is old-style lines below the turret. These are similar to what you find in the classic NXS model. If you compare it with other modern indicators found in the scopes of Leupold, Kahles, Hensoldt, Schmidt and Bender, Steiner, and other tactical riflescope manufacturers, this isn’t anywhere near that. If you can live with the old line indicators below the turret, this riflescope is surely one of the best in the tactical shooting category.
The elevation adjustment can be done easily without having the chances of accidental overrun. You can easily adjust the precisely carved 1 click adjustment knob. For adjusting the elevation, the torque required for the purpose is 3.6 inch-pounds. Most tactical shooters prefer this because they find 5.0 to be too heavy and at the same time 2.5 to be too light.
The clicks are distinct and crisp. You will hardly find any trouble in getting the clicks tight. However, you may get accidentally stop between the clicks. Stopping between the clicks are not only highly unusual but you also have to try to do it. Therefore, no matter what the situation you are in the field, you will always get the right adjustment with clear turret snap.
The parallax knob of Nightforce ATACR 5-25×56 doesn’t have distance markings on them. Most tactical shooters hardly need them because in virtual terms the adjustment markings hardly found to be exact. External factors such as temperature and others make the exact adjustments vary. Therefore, in such a case you can start hunting or any stage of a competition if you first preset the parallax to a ballpark distance. However, there are some who prefer indexes marked on parallax knob for having a prior idea of the distance you are focusing. In general, shooters don’t really need the markings on the parallax knob as they get the perfect focus by adjustment and clarity of image. Therefore, absence of markings on your Nightforce ATACR 5-25×56 hardly matters. The overall turret usability is average here.
