I recently bought a mag mostly for its body and barrel. Come to find out it has a Taso humpback on it that several people have told me has some rarity to it. I've had some people ask how much I want for the frame but I have no idea what it's worth. It's in pretty decent shape. Probably 8/10 with one small scratch on the bottom of the trigger guard. What should ask for it. I can get pics later. Thanks in advance.
