welcome to THR, congrats on the rifle, a fine one it is i might add. to answer your question. what range do you plan on shooting with it, and what is the main purpose of the rifle? I would suggest one of the super sniper scopes, if you don't mind fixed power scopes, and if so i would get a 4-12 otherwise, unless, you want more magnification, for hunting, let us know what you plan to do exactly and we can help you a little better.
