Depending on the model andgradeyou can figure to spend anything from $500.00 to $5,000.00 + on an A. Zoli shotgun. Try to get more information on the shotgun you're looking at and I can provide you with a better number. When you say "double" do you mean S/S or O/U?? I don't seem to remember a Zoli side by side, I thought they made O/U only but I could be wrong.....I am a lot!

Yes they are great guns.....
