lego gun shoots lego bullets

This is cool, especially if you're like me--and even though your prime Lego® years have passed you buy, you still can't get enough of them.  As a matter of fact, I'm working on the Lego® Death Star™ right now.  Using only Legos and rubber bands, Jack Streat was able to build a fully-functional  replica of a Heckler & Koch UMP 45 sub machine gun.
