Jason if you are interested in a 20ga Flues to put the barrels on contact me. I have decent one (#289100) that the barrel extension has came off and lost. I am not sure but I think these guns changed somewhat over time, whether the barrels are inter-changeable or not, not sure. At any rate I am sure we can work something out as I am never going to get to it for repair. My email is in my profile or PM.
