Does anybody have one a good, used .30-30 carbine barrel, or a good lead on one? Years ago (before the Encore) I saw barrel extensions to make super 14 barrels legal on the carbines. Does anybody know if they are legal if they are just attached with screws or setscrews? If so, I could have one made for my .30-30 super 14. It wouldn't be optimum, but will be at least as good as the pistol is, and that is good enough.
