Description
Vortex Sport Rings 30mm Low 0.80-Inch Pair
Vortex Sport Rings are low-height riflescope rings designed for compatible 30mm scope tubes and Picatinny or Weaver mounting bases. This configuration has a 0.80-inch / 20.32mm centre scope height and is supplied as a pair. It provides a defined mounting height for compatible riflescope installations.

Product Overview
These rings are part of the Vortex Sport Riflescope Rings line. The manufacturer identifies this configuration by the SPT30-L part number and lists the ring height as Low. Moreover, each ring weighs 1.54 ounces. The tube diameter, centre height, and mounting interface should therefore be checked against the intended riflescope, rail, and required objective-bell clearance before installation.
Key Features and Components
The rings use 6061 aluminum construction with a Type 2 low-glare matte black anodized finish. In addition, each ring incorporates an integrated recoil lug and laser-engraved torque specifications. Both the cap screws and base screws use a Torx T-25 bit. Furthermore, Vortex specifies 15–18 in-lbs of torque for the cap screws and 30 in-lbs for the base screws. These manufacturer-listed values provide the applicable hardware and installation references for this model.
