I have a Winchester 101 and the tubes are bored Skeet & Skeet. Now and then I can see on GunBroker that someone will be selling a 101 forend and barrels that are choked Mod & Full or some other combination. My question is - can I expect to be able to mount another barrel set on my 101 reciever group and expect it to function and function safely or do I need gunsmith intervention to check out the fit?
