This is a gun you would make if you want a fast build. I know this is an awful gun, so don't expect the best gun in the world here, O.K..
Step 1: Pieces You Need.
These are the pieces/things you will need to make this gun.
Step 2: Build This.
Build what you see in the picture below.
Step 3: Build This.
I now this picture is blurry, but build what is in the picture.
Step 4: Build This.
This what you should have now, also add the last three pieces to the far right, and also the shooting lever.
Step 5: Build This.
Now add the yellow bar, and the RAM pin which is the gray rod connect to the orange double connector.
Step 6: Build This.
For the last step attach the rubber band the yellow rod that the firing lever pivots on and, onto the open orange connector side.
Thank you for building this gun. :)
