Modular Driven Technologies offers their Premier Scope Rings, designed to provide precise interfacing and alignment with the scope tube. These rings are built to withstand heavy recoil and sustained fire, ensuring a rock-solid hold that won't lose zero. With a larger surface area, the clamping force is evenly distributed across the holding surface, maximizing the contact with the scope.

The rings are built to meet STANAG 4694 NATO specification, which means they sit tightly on the scope rail and apply equal pressure along the underside of the angled rail surface, maintaining a solid interface. This design also allows the scope rings to be mounted on out-of-spec rails.

These scope rings are sleek with curves that blend well into most scopes, made with superbly strong machined billet 6061 aluminum. In addition, the extra thick clamp system ensures that it won't bend, fatigue, or loosen after use. The Premier Scope Rings are machined in pairs for precise match and CMM checked to 0.0000015" for precision.

Tests have shown that the STANAG attachment method used by MDT's Premier Scope Rings increases the robustness of the interface, leading to increased alignment repeatability.
