Completely prevents ring-marks on your expensive scopes!
By putting a synthetic pivoting insert within a steel outer ring, your scope-to-ring surface area contact becomes virtually 100%. Prevent "Ring Marks" on the finish of the scope tube by using precision-made, tight-gripping inserts made of a dimensionally-stable synthetic material, the scope is not scratched or crushed which often occurs with conventional rings. With Signature Rings, when the scope is mounted in different positions or moved to another firearm, it still looks good as new -- also increasing the resale value of the scope. Self-aligning synthetic inserts pivot within the ring housings to eliminate any axial misalignment and induced stress on the scope.
