Many shooting enthusiasts stick with trips to the range or competitive shooting events. Others enjoy annual hunting seasons, and wait all year to appreciate nature from a blind or stand. A few hunters, however, take their expeditions a bit deeper into nature. Not content to stick with established paths or spots, they adventure through the back country in order to track their target. If your idea of a nature hike sends you to sites such as Cascade Mountain Tech for supplies, then our Mountain Tech line of scope rings has a lot to offer you. We engineered Warne Mountain Tech as a lightweight and rugged scope ring design that is equally at home on a mountain rifle or precision target rifle. We rely on high-quality 7075 aluminum, stainless steel hardware and an anodized hardcoat finish to produce rings that resist Mother Nature&';s wrath. The Mountain Tech 7213M 30mm scope rings have a low height, good for slim, compact hunting scopes. They can handle an objective of up to 42 mm. With a width of .705 inches, they can grip that scope&';s barrel securely and keep you on target. Weighing in at 3.5 ounces, they deliver long-lasting durability and performance, hunt after hunt.table.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }
