I bought my Nikon from Optic Zone and I'm buying my new rifle from Bass Pro next week. They're going to mount, loc-tite, and boresight my scope on my rifle for free. Then it's just a matter of me putting some rounds through it to make sure everything is lined up. You could probably take it to a Bass Pro if you have one in your area. They may charge you if you didn't buy anything there. Or a local gun shop. You should be able to find plenty of information and procedures for moutning scopes on the internet. Google it!
