Frequently Asked Questions

Does the set include one ring or a pair?

Product code S1300925 refers to a set consisting of two High rings. The pair required for mounting a scope is included in the package.

Do 25.4 mm and 1″ mean the same size?

Yes. One inch is exactly 25.4 mm. In product names, you may also see the rounded values 25 or 26 mm, but these rings are intended for 1″ main tube scopes.

How does the High version differ from the Low and Medium models?

The height of the High rings is 40.5 mm. The Medium version is 35.5 mm and the Low version is 30.5 mm. The High version raises the optic 5 mm higher than Medium and 10 mm higher than Low.

Are High rings suitable for a scope with a 56 mm objective?

They provide more clearance for large objective housings, but suitability cannot be guaranteed based on the 56 mm marking alone. You must check the actual external diameter of the objective housing, the base height, barrel profile, and the dimensions of the scope covers.

Are Optilock bases included?

No. This is a ring set. Optilock bases compatible with your rifle model and rail type must be selected separately.

Are the rings compatible with the dovetail base S13269738?

Yes. The S1300925 rings are compatible with the traditional Optilock base system, including the dovetail base S13269738 for Tikka and suitable Sako rifles.

Do the rings attach directly to a Picatinny rail?

No. The rings attach to compatible Optilock bases. For use with a Picatinny rail, you need the appropriate Optilock bases or rings designed specifically for direct Picatinny rail mounting.

What are the polymer inserts in the rings for?

Polymer inserts help align the scope, distribute mounting pressure, and reduce the risk of scratching or denting the scope tube.

When is the Optilock Sako/Tikka High 25.4 mm the right choice?

The High version is suitable when the objective housing, protective covers, or adjustment elements of a 25.4 mm main tube scope do not leave enough clearance with lower rings. Higher mounting may also be needed for rifles with a thicker barrel profile.

If Low or Medium rings leave enough room for the objective, it is better to choose the lower variant. A scope mounted too high can make cheek weld uncomfortable and make it harder to achieve a consistent shooting position. If necessary, you can use an adjustable cheek rest or a separate cheek riser with higher rings.

Expert recommendation

High rings often solve clearance issues with large objectives, but they should not be chosen just for extra margin. The optic should be mounted as low as possible while leaving safe clearance between the objective housing, scope covers, and the rifle. Measure the actual external diameter of your scope’s main tube and objective housing before purchase.

Before final tightening of the screws, set the eye relief in your usual shooting position. Check if your cheek rests naturally on the stock and if your eye is consistently aligned with the scope axis. If you need to raise your head noticeably to see through the scope, the Medium version or an adjustable cheek rest may provide a better solution.

Tighten mounting details gradually and to the torque recommended by the manufacturer. After installation, zero the rifle at the range and check after the first shooting sessions that the bases and rings have not shifted.

High Optilock steel rings for 1″ scopes

The Optilock S1300925 combines a 25.4 mm diameter suitable for your scope, 40.5 mm height, and a robust steel construction. It is the right choice when a large objective housing or rifle design requires more mounting space than Low or Medium rings provide.
