Point of order, your honor - the AR-7 does not fold up. The barrel and receiver unscrew from the stock and disappear inside. It thus presents a very innocuous appearance and is very lightweight. I have one of the vintage Armalites and it will float when properly encased. It is definitely a nice gadget.

Why not resurrect this thread? It is about guns, after all...Not as critical to most survival situations as some would have you believe, but still fun to discuss.
