Vortex Precision Matched Riflescope Ring Set

From Vortex:
We start with certified USA 7075 T6 billet aluminum and hold it to an extremely tight tolerance of .0005 using our precision Computer Numeric Controlled (CNC) mill. Our Precision Matched Rings are kept in pairs throughout the manufacturing process — ensuring perfection from one set to another. These Vortex rings are then serialized, vibratory tumbled, hand-bead blasted and finished off with a Type III hard coat anodize.
Rugged, lightweight, anti-snag design
Robust, Grade 8 fasteners
100% made in USA guaranteed for life
