Versatility is a small package, the Weaver Pivot Mount Rings make changing from scope to iron sights as easy as a flick of the wrist. Spring-loaded, they pivot aside with a gentle push. Yet a dependable spring latch locks rings in place when scope is in sighting position. Rings close with a solid "chock," letting you know your scope is back at zero. No Weaver Pivot Mount Ring requires drilling or tapping. High Pivot Mount Rings are 1/4" higher than the standard 1" ring, and provide plenty of clearance for scopes with objective diameters greater than 1-1/4".
