I recently bought a .17hmr with a Nikon prostaff scope. I have lost one of the turret caps. I contacted Nikon - they said go to dealer, went to rfd where purchased, he contacted them, they said you need an account (leads me to think the scope was used - that's a different story). So long story short my local rfd can't get the replacement and I need to get one. Can anyone help or advise.
