Here is my Star Trek First Contact phaser rifle. I am dying to buy the pieces I need to build this sucker. It measures about 25" long and is built with 457 pieces. It's only 4 studs wide. It could be a little thicker, but I think it looks great as is. I'd like to have opening panels to show some inner workings. I'm working on a tricorder from the same era. Should be fun.
