dont know much about this one, came through a trade and is missing its magazine. seems like a youth size semi auto is about as much as i can tell about it.
edit on closer inspection it might b a tube fed bottom ejected magazine. not 100 percent on that though and not going to try to fire it till i know more about it.
second edit looks like 139867 is the model number stamped on the bottom of the barrel but my google fu skills are not bringing anything up
