I'm looking for .22LR barrels that would be well-suited to "home-building" a single-shot, locked-breech gun without advanced machinery (i.e., no lathe or mill). (Yes, it's legal if it's not transferred or sold.)
I think a barrel with standardized male threads on the chamber end would be ideal, since an improvised "breech cap" with firing pin assembly could simply be screwed on over a loaded round.
I haven't come across any, but I'd be interested in seeing any common approaches to building such single-shot "zip guns" using a rifled barrel (as opposed to improvised smooth barrels). I'm not looking to reinvent the wheel.
