I have some extras for sale. I have a leather sling for a Swiss K31, and a the cleaning kit (though one bottle of Waffenfett is dented). Sling is in aright shape. I have treated it with leather protector to keep it a little more supple. Could probably use some saddle soap or Dr. Jackson's. Really not sure what the sling and cleaning kit are worth on their own. So, I am hazarding a guess, and gonna toss out $30 shipped? Or $25 local pickup? Or if someone has ammo in 5.56 or .308Nato to trade, I'd be down with that... I'd trade the cleaning kit straight across for a proper M16/M4 cleaning kit.
