Ring size determination - practical explanation

In most cases, quality rifle scopes have a wall thickness of about 3 mm.

Sample calculation:

• Objective diameter: 56 mm (e.g. 3-12×56)

• Wall thickness: 3 mm per side

👉 56 + 3 + 3 = 62 mm ring size.

So in this case choose a Rusan ARF135F155 in 62 mm.

On some cheaper riflescopes the wall thickness may be slightly larger. Therefore, always measure accurately or if in doubt, feel free to contact us for personal advice.
