Re: Can’t decide between Nightforce NXS 3-15 or 5.5-20
As I have relayed to others, yes, there is such a thing as too much magnification. That being said, I feel the 5.5-22x is the sweet spot because it allows you enough magnification on the lower end as well as on the upper end. With a 22x, you can always dial it down but with a 15x, you're stuck with 15x and that's it.
As for focal plane, you'll hear arguments on both sides of the aisle such as you can't accurately range with a 22x unless it's dialed up to the highest setting and that's because it's a second-focal-plane optic. With a first-focal-plane optic, you can range at any magnification. If the FFP is what you want, NightForce only offers the 3.5-15x at the present time. It has been rumored for quite some time, however, that NightForce will be releasing what many have referred to as "the beast" and it's expected to be a higher magnification, first focal plane optic.
Personally, I don't use my reticle for range estimation so I couldn't care less about whether or not I can range accurately with my reticle. For what it's worth, I've also noticed that the 5.5-22x are easier to sell when it comes time for an upgrade or you find that you're wanting to try something different.
As CSTACTICAL stated above, you can't go wrong with NightForce. If you decide you want something different after purchasing, you won't have a problem with reselling it.
Best of luck!
