Step 2Barrel and projectiles

Barrel and projectiles
Find the length that the barrel should be in your gun and cut it to the correct length. Find the projectile your are going to use, most likely a nail with a grounded down head, and position the coil so when the projectile end is at the very end off the barrel, the tip of the projectile is at the very begining of the coil. Last, put a stopper on the end of the barrel so that you may slide the projecile from the tip of the barrel.
