I'm a bit of a fanatic about optical quality - perhaps because I've been an amateur astronomer for a couple decades and have an observatory in the back yard.
I like Nightforce scopes - but they are, despite the usually 4 digit price, not known for having exceptional optics. You can get much better optics for less money and a Leupold VX- 2 has optics that are as good and the VX-3 optics are better – for a lot less money.
That’s probably heresy to say, as is pointing out that the optics in both the NXS and VHS series are the same. They are still very sharp and have excellent resolution and image brightness, however they have some issues with chromatic aberration and lack the contrast you expect at that price point and thus the optical quality doesn't impress the optical OCD in me. I can't comment on the ED glass ATACR series as I haven't owned or even tried one of them yet. The ED glass might make a difference in that regard.
However, what I do like about Nightforce scopes is the consistency, accuracy and repeatability of the adjustments, the alignment of the reticle with adjustments, and the range of adjustment. Even the less costly SHV series offers 100 MOA of elevation and 70 MOA of windage in the 4-14x56 model. For long range precision shooting precise, accurate and repeatable adjustments are absolutely critical to getting the first round on target.
I also like the reticle selections Nightforce offers, even though I still prefer MOA reticles and prefer second focal plane reticles.
Those factors basically drive my preference for a 4-14x56mm SHV with the MOAR reticle. It does everything I need it to do without making me pay for things I don’t want or use.
First focal plane (FFP) reticles are all the rage now as are Mil-Dot reticles, and that’s something that I find to be ironic given how the average owner of a FFP, Mil-Dot reticle scope uses it.
There’s no free lunch with a FFP reticle . The advantage of a FFP reticle is that the reticle subtends the same distance on the target regardless of the range. In other words, as the magnification increases and the target looks bigger in the scope, so does the reticle so that one mil dot or one MOA hash mark subtends the same distance on the target.
That’s very handy if you:
a) use the reticle for ranging and/or use the reticle for adding windage and elevation when shooting; AND
b) use different magnifications while doing that.
The downside however is that at higher magnifications the reticle starts to get very thick relative to the target and can obscure a small target at long range – exactly the time and place you’d use maximum magnification. At low magnifications the dots and hash marks as well as the cross hair starts to get very, very thin and hard to see, particularly in low light where you’re more likely to use low magnification, making an illuminated reticle almost essential. The end result is that the reticle thickness becomes a bit of a balancing act in the design looking for a sweet spot that will work at both high and low magnification.
The irony is that shooters gladly accept the downsides, often without really realizing they exist, and then seldom if ever use the scope in a manner where the FFP makes any positive contribution. If 90% of your long range shooting is done on maximum magnification, you don’t need the FFP feature.
Even more ironic are the shooters who get a Mil-Dot reticle and then work in yards and inches as it makes the math a lot harder than it needs to be. The Mil-Dot system is great and it makes the headwork very simple – provided that you are estimating ranges in meters and targets sizes in centimeters.
When estimating target range using a mil-dot reticle. The range in meters is equal to:
Target size in centimeters / Number of mils the target subtends x 10 = range in meters
For example if the target is 75cm tall and subtends 1.5 mil:
75/1.5 = 50, 50 x 10 = 500 meters; or
more practically in your head:
75/”15” = 5, then add back in the zero you took way ignoring the decimal to turn the “5” into a “50”, and finally 50 x 10 = 500 meters.
However if the shooter has a Mil-Dot reticle and is estimating target size in inches and range in yards, the math is much more complicated:
Target size in inches / target size in mils x 27.8 = range in yards
So…
18”/.8 mils = 22.5, 22.5 times 27.8 = 625 yards.
Sorry - I just can’t do that in my head.
Worse are the guys who want to use a mixed system with a Mil-Dot reticle and MOA adjustments on the scope. They have to apply a Mil to MOA correction on top of the already hard math, and they give up the ability to make the adjustment in the reticle. All that’s left is feeling cool because you have a Mil-Dot reticle (that you can’t use effectively).
The MOA system is also great – provided you are estimating target size in inches and range in yards.
Target size in inches / MOA subtended by the target x 100 = range in yards.
So, if a 30” target subtends 6 MOA in the reticle:
30/6 = 5, 5 x 100 = 500 yards
That math is dirt simple, even in your head.
Consequently, the system that works best for any individual is primarily dependent on what unit the individual is most comfortable using. The military likes mils and meters for standardization purposes with NATO allies, so mils and meters led to mil dot reticles in military service, and in typical military fashion with no particular concern given to ease of use for the solider using it.
However, because military shooters are “cool”, you’ll encounter civilian shooters who want to use what the military uses. But in the US they are usually Imperial unit people who may call a “yard” a meter and pretend to range in meters, but who also estimate target size in inches.
They struggle doing any of this range estimation math in their head, and generally just don’t do it - losing much of the utility the Mil Dot system provides in rapid shooting situations. They would have to give the up the mil-speaking cool factor, but they would be much better served with an MOA reticle.
However, if you want a challenge, try getting one of them to admit it in public…
