Head...I have a 3x9x33 Leupold VX-II Compact on my Remington 541-T....It came from the factory parallex adjusted for 150 yards....I sent it back to Leupold and they adjusted the parallex for me at 75 yards...I can't really say that it makes a great deal of difference but I wanted it changed...This is my main .22 for squirrels and I have killed many at 50 yards with this setup...I don't know if Nikon can have this done for you, might want to check it out...Good Luck
