Swiss Diopter Sights

TheK31 still remains popular for target shooting. However, the factory sights aren't very conducive to target shooting. As a result, the Swiss manufactured no-gunsmithing diopter sights for use with the K31.

The front sight simply slides over the factory front sight, and is screwed down. Note: in some cases shimming is required.

The front sight uses replaceable inserts. The inserts can be of the post or peep variety. The rear sight has an adjustable aperture.
Diopter sights are extremely difficult to come by in the states. They can be ordered from gunstores in Switzerland, but are quite expensive. Expect to pay at least $225 plus shipping.

The sight replaced the rear sight. The large box to the side is a battery to provide for low light usage. The tests proved unsuccessful, and the scope only saw limited production.

Other Solutions

As the Swiss solutions are rare and expensive, many individuals have come up with their own means of mounting scope. Note: most of the methods shown below permanently alter the rifle. SwissRifles.com neither condones nor condemns these alterations.

Adding target sights is a fairly common practice.
