Here is what I've found so far:
Any other weapon. - The term "any other weapon" means any weapon or device
capable of being concealed on the person from which a shot can be discharged through
the energy of an explosive, a pistol or revolver having a barrel with a smooth bore
designed or redesigned to fire a fixed shotgun shell, weapons with combination
shotgun and rifle barrels 12 inches or more, less than 18 inches in length, from
which only a single discharge can be made from either barrel without manual
reloading, and shall include any such weapon which may be readily restored to fire.
Such term shall not include a pistol or a revolver having a rifled bore, or rifled
bores, or weapons designed, made, or intended to be fired from the shoulder and not
capable of firing fixed ammunition.
From what I see here, it's not classified as AOW. I'll look some more and post my findings. I appreciate this being brought up. I try to keep my stuff as legal as possible. I like to be able to shoot my stuff and not worry about going to jail.
