"BP guns here are firearms for legal purposes. Some of the newer inline guns have thumbhole stocks. Some changes might happen if certain "appearance" standards get acted on. Many musket models have bayonet lugs, etc. Spooky times we live in."
Indeed...yet Cabelas is able to ship blackpowder firearms right to my doorstep via UPS...how does that work? Because while Illinois views BP as a "firearm", BATF does not, if I am correct.
