Lego Pistol

Hi guys this is one of my entry's for the toy contest so please vote when time comes!!!
OK this gun will shoot anything you can fit in the barrel but i like to shoot 2x2 bricks best. It works the same as most knex guns: Ram gets pulled back > Trigger gets in the way ram rod > Ram rod stays there > Trigger pulled > Ram rod goes forward taking anything in the barrel with it (bullet) and propelling it out the barrel.
