I don't have a 15-55 but I have a few BR 12x42 from my F-Class days. Put one on a FX Streamline and it works great. Only thing is that I would not use it for a stalk type hunt (bench shooting hosps fine) when I'm walking I prefer a 4 or 6 power scope
Yes I have two, the dot and the ladder rets, fantastic scopes and actually better optically IMO than all 3 ATACRS I have and not only mine as others have looked at them together as well.
Thanks for the replys, unfortunately this scope will not focus under 25yds, and after contacting Nightforce, they will not special order it to focus down any closer. To bad as they make great scopes.
