Description Key Features : Dedicated CZ 550/19mm Dovetail Fit: Precision-machined to match the exact profile of the 19 mm receiver dovetail, ensuring zero movement and maximum contact area. These rings are a direct, custom fit, unlike universal mounts. 30 mm Standard Diameter: Perfectly sized to securely hold the vast majority of modern riflescopes, thermal, and night vision Optics with a 30 mm main tube diameter Thumb Screw Attachment (Tool-Less): Utilizes robust thumb screws for hand-tightening, allowing for quick and easy removal or adjustment in the field without requiring tools. This is a practical compromise between a permanent screw mount and a full Quick-Release lever system. Medium Height (H15): The 15 mm height (measured from the top of the dovetail to the center of the scope tube) is categorized as a medium height, providing sufficient clearance for most medium to large objective lenses (typically up to 50 mm) while keeping the optic low for optimal shooter ergonomics. Roll-Off Design: The two-piece ring design installs via a “roll-off” motion onto the dovetail, providing a highly secure mechanical lock-up when tightened. Steel Construction: Made from high-quality, CNC-machined steel to ensure exceptional rigidity, durability, and recoil resistance, backed by Rusan’s reputation for quality.
