7,
It may have the bases mounted on the receiver wrong, take the scope and rings off, and see if you can either swap the front and rear bases, or turn them around to gain some front to back clearence on the scope bells. Some bases have more than one notch for the Weaver style recoil cross bolt on the ring.
If you have to swap the bases to get the proper fit make sure to clean out the threaded holes in the receiver with alcohol and Q tips. They usually don't do that if its a pacakage rifle.
Clean all the mounting surfaces,and I use some blue Loctite on the base to receiver screws.
If you have a gun type screw driver kit have at it. If not go back and buy one, or go to Wallys place and they have an inexpensive one there under 10 bucks.It will keep you from sctatching your new set up. Household drivers don't fit the screws properly.
If for some reason you can't gain enough eye releif, you will have to buy the correct bases or off set rings.
The 7mm mag recoil requires that you have at a minimum 3 inches of eye releif to keep the scope from recoiling into the eyebrow (red eyebrow). I would like to have more.
It takes some time to get the scope set up just the way you need to on some rifles don't get discouraged or worse yet rush the job, take your time and figure it out it's just a big puzzle to solve.
You may have to get a different mount ring set up, but one plus is you gain the experiance, and you get to check out more rifle related stuff!
