The Ncstar Hunter Series 3/8'' Dovetail 1'' Rings - 1.3''H are precision optic mounting rings designed to fit 3/8'' dovetail rails and secure a 1'' diameter scope with reliable alignment. Featuring an optic centerline height of 1.3 inches above the rail, these rings keep your sightline true for improved point-of-impact consistency across movement and elevation adjustments. The hexagon-shaped mounting nut includes holes for torquing with an Allan key wrench, enabling quick, tool-controlled installation and consistent clamping pressure to protect optic tubes from slippage or damage. Constructed to balance durability with versatility, they provide a solid, repeatable platform for hunting, tactical training, and range work, ensuring your optic remains stable under recoil and field conditions. The design supports repeatable zeroing and maintenance, while the 1-inch ring diameter accommodates a wide range of standard scopes, allowing you to upgrade optics without changing the mounting system. With Ncstars Hunter Series, you gain a clean, professional mounting solution that emphasizes precision, ease of use, and dependable performance in real-world hunting and shooting scenarios.
