Vortex scope rings provide a medium-height mounting solution for riflescopes with a 1-inch tube. The SPT1-M configuration uses a 0.90-inch center scope height and fits Picatinny/Weaver mounting interfaces. Therefore, it belongs in the riflescope ring and mount accessory category. The manufacturer lists the medium version at 1.76 oz. per ring.

These Vortex scope rings combine a 1-inch tube size with a medium ring height. The mount type is listed as Picatinny/Weaver. Moreover, the manufacturer specifies Torx T-25 fasteners for both the cap screws and base screws. The listed cap screw torque is 15–18 in-lbs., while the base screw torque is 30 in-lbs. These values provide product-specific references for installation.
Key Features and Components
The rings use 6061 aluminum construction. In addition, they have a Type 2 low-glare matte black anodized finish. Laser-engraved torque specifications place the relevant installation values directly on the product. Furthermore, the 0.90-inch center scope height identifies the medium configuration. The combination of a 1-inch ring size and Picatinny/Weaver mounting format defines the model’s compatibility requirements.
