The Recknagel Tip-Off Rings and Bases System is a modular, precision-engineered solution for owners of traditional bolt-action rifles who demand a quick-detachable scope without sacrificing accuracy. These rings are designed to lock onto semi-permanently mounted Recknagel Tip-Off Bases (sold separately to fit your specific rifle action), creating a flexible and highly repeatable mounting platform. The 30 mm ring diameter and 17.5mm height are ideal for most hunting and medium-objective tactical scopes.
