I bought a Nerf gun. Ya, that's right. It happens to be the CS-6 Longshot. Seeing as how it's a sniper rifle, I figured it could stand to shoot like one, too. So far all it does is shoot a little foam dart about 30-40 feet max, and I really want it to go more like, 100 feet. It sure would be nice if I could leave welts on my friends, too. So, check it out, all you need is a little time, patience, spring, o-ring, and sealer-stuff.
Step 1: Disassembly
Basically, the gun's held together with A THOUSAND screws. They're sort of small, phillips head screws. Some are longer than others, mainly the front 2, so try to keep track of where they go. If you need help, try what I did by laying them out in the shape of the gun. The only hard part about taking it apart is that dang bolt. It's the big orange thing you use to cock it. You can remove it by carefully prying it with a wide, flat-bladed screwdriver. As is true with what seems like all Nerf guns, they're just screwed together.
