Nerf reactor to shoot nerf dart mod

Step 2 Fitting the barrel

now once you have cut the reactor barrel, the giant spring and the orange thing on it should come out. the spring is totally useless here, but u should keep the orange thing. you need to cut out the center of the orange thing so your barrel fits tightly in it. then you should glue it onto the end of the barrel. and you also have to take the other end of the barrel, put some glue around the bottom of it, and stick it down into the barrel of the reactor so it fits into the little hole at the end of the barrel. (this part is optional but u can also cut off the little black air restrictor thingy and the orange thing sticking out the back of it) and if you can u can also put a tiny bit of glue on the inside of where you glued in the barrel ( just to make sure there arnt any air leaks and that it stays in)
