I am in the process of emptying out my safe and was considering parting with my K31 since I don't get around to shooting it. The rifle itself is in very good shape, I purchased it in 05 from AIM. The value comes from the Diopter I purchased from the Wyss Waffen store during a trip to Switzerland. I am having a hard time finding any information (in English). Here are links to the 3 parts I have.

CENTRA Iris-Ringkorn 2,5-5,0mm - Karabiner 31 - Waffenzubehör
the adjustable front peep sight.

WYSS Tunnel W1 Karabiner 31 - Karabiner 31 - Waffenzubehör
the front tube sight. Installed with no gunsmithing!

WYSS Diopter W Karabiner 31 - Karabiner 31 - Waffenzubehör
-the rear peep sight.

I have fired the gun but not with the peep sight installed. How much could I sell this rifle for and where would be a good place to do so. I live in CA.

I took a few pictures to help. Thanks for any advice.

On the swiss boards, the diopters sell for about $650. You might find more info there if you would like to check.
