I have a beretta S686 "special" that a friend of mine wants to sell. I can't seem to find a value anywhere as to what they sell for. It seems like the blue book says 900.00 ish at 100% but I know the blue book isn't always rite when it comes to sale value. It is a beretta s686 with 28" beretta/benelli choke threads. Blueing seems to be about 90% and a few handling marks on the stock. The original butt pad is there but rough around the edges. Other than that the gun seems to be in great shape and the open lever is about 1/16" off right center. What do you guys think this gun is worth?
