Scope Base Mount for Schmidt Rubin K31.  

This two-pieces weaver base (21 mm) is constructed of steel.

It is fitted on by inserting its front part in place of the rear sight, using the same pin, and in the rear part locking it by means of a steel grain (supplied) against the upper part of the cartridge chamber (see photos).

It accepts all Weaver Top Mount Rings and accommodates the mounting of devices such as scopes, red dots and laser optics.

Require proper fitting.
