When you are building a precision rifle around a classic 1-inch tube diameter, the quality of your mounting hardware is the deciding factor in your long-range success. The Vortex Precision Matched rings (MPN: PMR-01-76-W) represent the pinnacle of mounting technology. Unlike standard production rings, these Vortex matched rings are kept as serialized pairs throughout the entire CNC-machining process. This ensures that both rings are perfectly concentric to one another, providing a uniform grip that eliminates the need for lapping and prevents the internal stress that causes tracking errors in your scope. Machined from a solid block of 7075-T6 billet aluminum, these 1 inch scope rings offer the durability of steel without added weight. With a low-profile height of .76 inches, they are designed to keep your optic as close to the bore as possible, favoring a more natural cheek weld and better balance for hunting and target rifles alike. These Vortex PMR rings undergo a rigorous finishing process—vibratory tumbling and bead blasting—and receiving a Type III hard-coat anodization, they provide a snag-free, low-glare finish that withstands harsh environments, ensuring lasting reliability in the field. To ensure your system remains rock-solid through heavy recoil, following the professional torque specifications is vital. For these Vortex rings 1 inch, Vortex recommends tightening the base clamp screws to 45–50 in-lbs and the ring cap screws to 15–18 in-lbs. This precise tension ensures your optic stays locked in place without marring the finish. At EuroOptic, we know that a world-class rifle deserves Vortex precision rings. Trust the PMR series to maintain your zero, shot after shot. Vortex Optics Vortex Precision Matched Rings (Set of 2) 1-Inch (.76 Inch / 19.3 mm) Weaver PMR-01-76-W
