However, is it smart to? Probalby not. Not just from a legal standpoint either. Would be wiser to disassemble your marker and put it in a backpack or even a couple of doubled up grocery bags.
Plus I wouldn't really want to walk down a street caring my gun, barrel, tank, and hopper all my arms. I'd be too afraid of dropping something on payment and breaking it not to mention that would just suck to carry like that. Definitely going in a bag.
