Re: ATACR vs NXS 32X on 25X eye releif?
The ATACR can be had with the MOAR-T reticle which has a fine center cross hair, I have yet to shoot one but it should be ideal.
If your set up is correct you should not be straining anything, especially with a Nightforce since the eye box is typically very forgiving, to me it sounds like your needing to adjust the stock or the optics mounting more than anything. I would still roll a ATACR on it just for the better glass and more MOA.
