Step 8: Loading and Shooting
Take a rubber band (the best ones to use are said in the next step) and put it from the two green prongs in the front (picture 2) to the space in the back of the yellow connector that you just put near the back. BE CAREFUL! Press on the orange connectors to keep the yellow piece from sliding out.
After the rubber band's on, slowly remove your hand from the orange connectors and pull the trigger!
Step 9: Tips
Replacing Ammunition: If the trigger seems very sensitive, replace the ammunition. Also, this gun has a huge reputation of breaking the ammo. Make sure you have a lot!
If you find anything wrong with the documentation or the gun (primarily the trigger), please tell me about it.
