ORS 166.272 - Unlawful possession of machine guns, certain short-barreled firearms and firearms silencers - 2013 Oregon Revised Statutes (http://www.oregonlaws.org/ors/166.272) "Unlawful possession of a machine gun, short-barreled rifle, short-barreled shotgun or firearms silencer is a Class B felony." ORS 166.210 - Definitions - 2013 Oregon Revised Statutes (http://www.oregonlaws.org/ors/166.210) Here is the questionable part: "Short-barreled shotgun means a shotgun having one or more barrels less than 18 inches in length and any weapon made from a shotgun if the weapon has an overall length of less than 26 inches." So - is the definition of a SBS in Oregon law that a "short-barreled" shotgun is a shotgun with a barrel less than 18" and OAL of less than 26"? Or is that a "short-barreled" shotgun is a shotgun with a barrel less than 18" or OAL of less than 26"? I am thinking the former - hence the use of the word "and" - but I am not sure. This is where I am thinking some people will get tripped up on some of these "loopholes" in federal laws and BATF policy/rules/etc.; that they have to meet both federal and state law, and that state laws don't always have the same definitions/etc. as the federal laws - i.e., what is an SBR or SBS or "firearm" or AOW, etc., doesn't always match the federal laws or BATF interpretations.
