I have figured out something useful without making the firefly ugly. First, take out all of the screws, and start mapping them by the nerf's shape. Sorry I have no pics, but I want this to not take three days. Take out the pieces that support the barrel. Draw a map if you have to, because this can get very annoying to put back. take out the barrel with the supporting orange piece and throw away the orange front piece. This may reduce slight accuracy, but you can now use sonic micro darts, and you need to to do my 3rd to next mod. Unscrew the back of the barrel. take out the piece. Unscrew the 3 screws on the back, too. Make sure to keep mapping. Unsrew the last front screws. Get small pliers or a large screwdriver and pry it open, going all around. Take out the springs and the 3-pronged pieces. Put the barrel back together. Take out the air pump and stretch the spring. Put back the gun, using your mapping. Now, for the fun part. Drill a hole through the center of the barrel, big enough for your flashlight. You are done. Have fun.
