Yes, It's Illegal. at least in the USA

This picture was emailed to me -
The person sending it wanted to know two things:
1. Is it illegal to own?
2. Could I identify the rifle?
The first question is answered, although there's law that covers overall length, but this cut down weapon doesn't appear to meet that minimum criteria.
As for identifying the rifle, no I cannot, it is definitely a bolt action with the barrel cut off at the stock. It could also be a shotgun, such as an old 410 gauge bolt-action type.
If anyone knows what this is, please let us all know.
















I did not post to Twitter yesterday because I was having Google issues. Google is still a little quirky today, that's why I am posting late.
