I was talking with some folks at the range the other day. It turns out that some of these guys actually carry a rifle (unloaded) in their EDC bags/packs. Their pistols are carry concealed in the usual way. But the rifles are there for bigger fights, such as active shooter scenarios, civil unrest, etc. I live in an urban environment where you get from point A to point B by foot or public transport. In a way, these "bag guns" are the urban equivalent of the truck gun. In my state, you can conceal a loaded AR Pistol, SBR, and (ironically) machine gun. You can also transport a rifle, such as a full size AR, but it must be unloaded. In this case, the AR is broken down to fit in the pack anyway. Mags can be loaded, but must be stored in a separate compartment than the rifle.
