How did you make the rapid fire gun? get back to me on that but anyway good job on the clone :]
Okay, so first you take a blaster gun,(like the ones on lego star wars 2) then take the piece that you connect with and add a handle piece. Then, add one of the pieces with a rod-like piece, with a connecter on the end. Simply push the end into the front of the gun, then add whatever weapon accessory you want to! TA-DA!
