hese rings let you choose between a quick iron sight shot or using the scope. For 1" scope tubes only. No base is required. This mount will position the scope about 7/8" above the receiver. 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.
Fits: Ruger 77
Notes: These bases fir the new model 77 with an integral sight base, not the older round top configuration. The older model uses the two piece bases #79 and #35.
