Good advice in this thread.

If you have no previous experience mounting scopes then I think $17.50 is a small price to pay for the confidence that the scope is mounted correctly.

If you decide to do it, use Lock-tite on all the screws. Mount the bottom half of the rings to the bases and make absolutely sure that the rings are in perfect alignment by sliding the scope up and down (there is actually a tool gunsmiths use to ensure alignment).Regardless ofwhich type of set-up you use (one piece, two piece, Redfield or Weaver style, detachable or permanent) they must be aligned perfectly. When you attach the top half of the rings make sure that all the screws are seated to the same depth and the rings are tightened down equally. Boresighting is easy if you have a solid rest or gun vise.

Good luck
