The Quick Release Mounting Rings 25.4 mm Medium from Konus consists of two medium mounting rings with which you can easily mount your rifle scope on a rifle. These rings are suitable for tubes with a thickness of 25.4 mm and are compatible with Weaver and Picatinny rails. The Konus Quick Release Mounting Rings Medium allow you to mount the centre of the mounting rings at a height of 21.2 mm above the rails. This allows you to use rifle scopes with a maximum lens diameter of 40 mm.
