So as I'm sure many of you knOw there is a briefcase you can buy for an MP5K or semi auto clone that allows you to shoot your firearm from the briefcase. However, when you use this you must register your pistol as an AOW. My question is this, would it be legal to "open carry" your briefcase since it would be registered as an AOW even though the pistol is technically concealed inside? I ask because Oregon only allows concealed handguns and I don't believe an AOW would fall into the general term for handgun. Thoughts, comments? Just google mp5k briefcase if you don't know what I'm talking about.
