I can see where the confusion may be, the Blue Sign states: " The unlicensed possession of a weapon on these premises is a felony". Key word being "unlicensed." A person carrying a rifle is carrying an unlicensed firearm, as there is no requirement or option to license a rifle except for hunting, then it's not the firearm but the person that is being licensed to hunt. To this date, to the best of my knowledge, the only licensing to carry a firearm is for concealed handgun carry, security or LEO.

The sign does say weapon so if you carried a rock into the store and acted unfavorably you could be in trouble also. Felony for carrying a rock.
