*can be substituted for similar pieces

The rubber band should not be streatched to its fullest; if it is, connect two together instead.

Step 15: Prepare to fire

Picture of Prepare to fire

Load ammo, pull back pin until it locks in place, and fire.
If it jams, pull back the pin until it locks. Check that the ammo is in place to be fired, and try again.
If the pin doesn't lock, adjust the rubber band shown in step 13, picture 7.


Note: the more ammo you put inside, the less well it works.

If you guys want people to take any of the knex posts seriously, I suggest you act a little more mature, or at least take it to your own instructable.

Are the spacers at the bottom rod neccessary? Or are they just there to keep the other two rods from getting too close to each other?
