This is my first rubber band gun and my first LEGO gun ever uploaded on the Internet, an FN Five-seveN semiautomatic pistol (should be regarded as the "Belgian Deagle"). It took me 1 day to make and the 2 white small rubber bands are used for the trigger. If you're wondering why there is the "wheel" on the trigger, it prevents the trigger from moving forward too far. It can shoot maybe 3 or 2 rubber bands but I usually shoot 1. Instead, I'll try shooting more than 1. The P90 was introduced in 1990, and the Five-seven was introduced in 1998 as a pistol using the same 5.7x28mm ammunition. Please rate and comment.
