I have been searching for aTrade Gun - Smoothbore - Octagon to Round barrel - 20 Ga 36 inch. I have noticed that most places have extremely limited stock on smooth bore barrels. I see a 3 - 9 month lead time to get a barrel from most of the reputable sources. For us uninformed types, If I order a barrel I assume the barrel maker orders a barrel blank from someone and then finishes the barrel that I ordered. I am just trying to understand the 9 month lead time. Is this because there is a very long list of orders? I have no idea how many hours it take to make a barrel.
