Re: Top of the line IOR verses Nightforce NXS ?
I have several of both IOR and NF. What I like most about NF is their durability, tracking reliability, parallex adjustment- it has a much larger range and sensitivity than the IOR. What I like about the IOR is the elevation knob - 25MOA's per turn, the reticle, just love the MP8, slightly better glass although after replacing a defective IOR{parallax kept going out of focus} the new one doesn't seem as clear as my NF's. My other IOR's are slightly better optically than the NF's, especially my 4-28x56 IOR. I prefer MOA scopes and had a NF with the NP-R1 and had a real difficult time focusing the reticle, ended up sending it back and had a MD put in. If NF ever got a larger range Elev knob, I think I would change all my scopes to that.
