The MDT Elite Scope Rings offer a solid, lightweight mounting system for your optics. Made from precision-machined aluminum, they are available in 30mm, 34mm and 35mm diameters. The two diameter options are available in four different heights (measured from top of rail to center of bore). SPECIFICATIONS Designed for ultimate precision and strength 25mm (0.984”) of lateral contact with scope tube 30mm (1.181”) of lateral contact with mounting rail The main body is machined on an automated seven-axis, high-end CNC machine tool Extra wide profile provides extremely stable mounting The bottom rail interface is machined at the same time as the scope clamp interface, guaranteeing all rings are square and parallel CMM checked to 1.5 millionths of an inch precision Machined from Billet 7075-T651 Aluminum – 1/3 the weight of steel with similar strength Extra thick clamp system will never bend, fatigue, or become loose with use Built-in bubble level on medium, high, and extra-high rings (No bubble level on low rings) Stepped base-to-cap interface allows the fasteners on one side to be tightened before making final scope alignment adjustments Six oversized #8-32 Grade 8 fasteners used for clamping the scope Sleek curves blend well into most scopes MDT Precision Scope Rings are designed and manufactured to STANAG 4694 specification, also known as “NATO spec”. This means the scope ring sits tight to the top of the scope base rail, with pressure being applied to the underside of the angled rail surfaces to maintain a solid interface. This design also allows mounting on out-of-spec rails: MDT Elite Scope Rings Clamp By contrast, US MIL-STD-1913 spec mounts attach only to the angles sides of the rail, leaving a small gap between the top of the rail and the underside of the mount, and significantly reducing the amount of contact area between the mount and rail: MDT Premier Scope Rings Other Testing performed by NATO has shown that the STANAG attachment method increases the robustness of the interface, leading to increased alignment repeatability. MDT Elite Precision Scope rings can be mounted to scope base rails designed to both the STANAG and MIL-STD specifications.
