i agree with others, save your money. if you have a bolt action bore sight it with your eye's. bore sighters have never impressed me. the last 2 rifles i bought were "professionally" bore sighted by 2 different gun shops and neither one was even close. i wasn't even on paper, it took a box of shells to get them on paper. i've never had a scope out of the box as far off as the 2 rifles i had "bore sighted".
