Following along with this, if I were to make an insert that chambered .410 shotgun shells and that insert slipped into a metal-framed 25mm marine signal flare gun, would I be in violation of any laws??
Since it was never a "shotgun", I don't think it can become a shotgun just because I drop a brass adapter into it...
I know the BATF will pass up no opportunity to use the sawed off shotgun law against anyone they can so I don't want to fall into that trap...
Any thoughts?
