Machined from a solid piece of steel, the 1" Signature Zee Rings for Mounting Riflescopes from Burris Optics offer precision, strength, and durability. They hold your scope at 0.92" height and feature a Weaver style adapter and 1" riflescope maintube compatibility. These rings also include Pos-Align inserts that improve centering and maximize scope-to-ring contact, which improves gripping power without damaging your scope's finish.
