To reliably install an optical sight or additional optical devices with a diameter of the tube 30mm, the best way to install will be steel rings. The main benefits of steel rings:
- hard landing on the weaver strap
- resistance to vibrations when shot
- mechanism of rapid removal of sight
There are 3 types of height of steel rings, the height is measured from landing on the weaver to the place of laying the sight tube. This type of rings are average.
