The Sun Optics USA Standard Sport Aluminum Riflescope Rings feature a wraparound design that minimizes pressure on your scope tube while ensuring a secure hold. These black matte-finish rings are equipped with four Torx cap screws for a firm closure and a steel recoil key to handle the recoil of repeated shots. Thumb nuts allow for easy, finger-tight installation, making them ideal for use at the range or in the field.
