Warne Mountain Tech rings are the ultimate in a lightweight precision scope mounting ring. These rings are precision CNC machined from 7075/T6 aluminum for strength and durability. A Mil-spec hard coat anodized finish will ensure that your rings will resist abrasions and corrosion. The hardware is also made from stainless steel as additional reassurance against the elements. The Mountain Tech rings allow for a superior connection between ring and rail. It is recommended that you use a Torque wrench to apply the correct amount of torque in inch pounds.
