The Konus mounting rings 30 mm Medium consist 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 diameter of 30 mm and are compatible with Weaver and Picatinny rails. With the Konus Mounting Rings Medium you attach the center of the mounting rings at 23.6 mm height above the rails. This allows you to use rifle scopes with a maximum lens diameter of 44 mm.
