I have had several handi Rifles before but never did the barrel swapping. I like Thompson Contenders as they have the interchagable barrels.
So now I want to do the Handi Rifle with different barrels. I need to know how to tell them apart. I was told that all rimfire and shotguns come with the SB1 receiver. I also read somewhere that the serial number would tell you the year made and that some years models will not interchange. Can someone point me in the right direction as this is something I am going to start collecting. Thanks for the advice.
