Our proprietary steel alloy ALPHA Hunting Rings are machined with an exactness that is both strong yet ductile that allows our rings to form around a riflescope, yet will not damage scope under proper installation. The steel rings are epoxy powder coated to prevent oxidation and resist gun oils, cleaning solutions, and outdoor exposure.
