I have heard that the Micromag and autococker barrels are interchangable? anyone know for sure?

ummmmm....... i dont think they have the same thread. because when u go to pb sites and go into the barrel section. and they ask what kind of gun. they usually group the same threads together. like spyder/pirahna/rebel.

I am not sure ethier but i think Kapp makes or use to make an addpter for ethier auto coeker barrels or Spyder..ill look into it for ya.

And the addapter looked really nice on the mini`s too
