These Quick-Detachable, steel rings allow you to easily remove and replace your scope with virtually no loss of zero. Perfect for transportation, or for using one scope on multiple rifles. Due to the contour of the Ruger 77 action, rings for this rifle are not the same heights. The manufacturer makes the rings to ensure your scope is level with the bore.
Ring Height: High: .585"; Medium: .460" (measured from base of ring to bottom of scope tube)
