I have/had three NXS scopes, two with MOAR and one with IHR and without illumination the reticle's are very difficult to see at last light. I agree with CFVA that my experience with Leupold VX3's are they are just as bright, if not brighter, than the 2.5-10x42 NXS. The NXS scopes maintain zero once set and I have not been able to say the same for most of the many Leupolds I have had.
