My experience is both extensive and very postive. Setting the illuminated reticle is a pain since very minor adjustments result in significant changes in intensity; however, once set, it is unobtrusive, very effective, and works well. I have several friends who shoot long-range precion and, after shooting mine, at least 3 of 5 have traded in their glass for nightforce (not the S&B guy and not one USO.)
My only other gripe would be that the entire occular rotates when you cahnge power. A field-expedience solution is to add a Bulter Creek Blizzard occular cap. The opening doesn't have the same button as the normal and is lower profile so the rotating occular isn't an issue. Also, it's clear so you can leave it down and shoot through.
Th glass is very good, the construction is very solid, and reticle is great. Some here will disagree, say you should'a bought a leupy or Zeiss or IOR or USO. I've owned/used all but IOR and bought the Nightforce. You made the right decision in my book.
I too have the 50mm and it mounts fine on a PSS with medium Badger rings in a 20 degree base.
Congratulations, you'll love it (once you set the illumination.)
