About this creation
How it works: In the picture showing the front of the gun, there is a small slot where a rubber band is inserted. You flip up the sights, chamber, and red dot to pull the rubber band back to the wheel (tan colored as seen in the picture.) The trigger holds the wheel in place because on the back of the gun, the shells(the 2x3 flat black pieces with yellow vent-like pieces on them)go on the trigger and the yellow part goes into slots of the wheel while the trigger is held up by inserting a rubber band in the grey slot in front of the trigger. Pieces to shoot are easiest kept at the end of the gun, where you flip up a door and inside you can store tons of pieces. you put the piece in front of the wheel so the rubber band holds the piece. You then flip the sights back up, along with the chamber and red dot to make it more accurate. when you pull the trigger, it releases the wheel, which releases the rubber band, which takes the piece and shoots it down the gun and releases it because the rubber band is held back. That is the best explanation i have for you. use the pictures to help yourself figure out how it works. This was not built to look exactly like the gun.
