this gun is easy to make and does not take alot of peices to make it...sorry about the block trigger.
Step 1: Handle
pieces 7-corner connectors and 2-blue rods... this step is very easy-sorry about the bleary pics
Step 2: Ram
this is also very easy but on the part were the rod connects to the connector piece you have to put tape on or it will back fire.
Step 3: Barrel
build this. it is a little harder
Step 4: Put It Together
put it together- this is also the step were you add 2 rubber bands.
