Depends on condition! Rule of thumb - about $50-$150 It also depends on how much you want one. In like new condition they will go higher if you want one bad enough. I recently bought a Revelation 16 ga. {made by mossberg) in used but not abused condition that looks good and didn't mind paying $125 I hope this helps you out!
