Can't go wrong with the Nikon . I have the m223 on my ar and pro staff 3-9 x40 on savage mkll fv with bdc . Love em both for the price. Next I want a higher power pro staff for my new savage hog in .308 for LR target.great software you can use on your smart phone also.
I have a Prostaff on my 30-06 my 308 and my 50 caL ML. I think Nikon is a great choice in optics they give a great value and work very well and they come with a lifetime warrantee you wont have to use.
The Nikon P-223 is a great scope and have a few of them. See attached pics. The M-223 is really nice as well especially with BDC
