Step 4 Cleaning and adding barrel

now try pumping and shooting you gun to make sure it fires, you also should probably wrinse out the plastic scraps from the sanding and sawing to make sure the gun works well and still shoots. so just run a little water onto the black rubber peice down the hole on your gun and just shake the water out. now get your barrel, it can be anywhere from 2 1/2 in to 3 1/2 in, mine is 3 in.  now put your barrel onto the area where the old barrel was and make sure it fits well. then glue it in place, make sure it's straight and flat up against the back. careful not to melt the plastic if your using a hot glue gun. also put quite a bit of glue between your barrel and the pump, (ontop of the plastic strip between the barrel and the pump to give the barrel more support)
