Thor 25mm High Stud Type Rings

The Thor 25mm High Stud Type Rings provide a high-profile mounting option for a scope with a nominal 25 mm tube. Before choosing them, confirm that your scope uses the correct tube diameter and that your rifle has a compatible stud-type base. The product name identifies the ring height and mounting style, but it does not confirm the ring material or exact height measurement.

Thor 25mm High Stud Type Rings

These rings use a stud-type mounting interface rather than a universal rail clamp. Therefore, check the existing bases on your rifle and compare their stud layout with the product before installation. However, do not assume that stud-type rings will fit a Weaver or Picatinny rail, because those systems use different mounting interfaces.

The 25 mm designation refers to the scope tube. Since some manufacturers describe one-inch tubes as 25 mm, check the scope maker’s specification before fitting the rings; one inch equals 25.4 mm. In addition, a scope tube that measures 30 mm or 34 mm needs a different ring diameter.

The high profile places the scope higher than a low or medium set. As a result, it may provide extra room around a larger objective bell or a rifle with limited clearance above the barrel. Nevertheless, the correct height depends on the scope’s objective diameter, barrel contour, bolt handle and stock shape. For example, a high ring set can solve a clearance issue, but it can also raise the scope above a comfortable cheek position.

Before tightening the rings, check that both rings match the bases and sit securely. Then position the scope to achieve comfortable eye relief and a level reticle. Also, cycle the bolt and inspect the gap between the objective bell and barrel. Finally, follow the ring maker’s fitting instructions and use the specified fastener torque if the manufacturer provides it.
