Most knex guns are very loud, because of the ram rod hitting against the body of the gun. To silence it, you must put a cushion between the body and the ram rod. I used bakenbitz's BBKWG gun for tis instrucable. (nice gun)
Step 1: Materials
A knex gun: Find one that's ram rod hits the bullet fully, instead of just touching the edge of the bullet
Step 2: The Cushion
Fold the tissue into a decent size for your gun. If you need help, comment of the problem.
After that, create a hole for the ram rod with your scissors.
Step 3: Tape It On
First, remove the ram rod.
Then tape the cushion on so the hole matches with the hole in the gun.
Tape it down good.
Then you put the ram rod back.
