I went ahead and modified my little brother's Nerf HyperSight, or Expand-a-Blast last night, but I came upon a problem, no spring. Where can I find a stronger spring for the gun. On the cxwq mod he said he got the spring at OHS, and being the newbie I am, I have no idea what that means.
I recently bought a RapidFire 20, my first nerf gun, for a town Nerf war. I haven't been too happy with the range it gets, so I talked to a friend who directed me to this site. I'm looking for something a "n00b" can do to a RP 20 with relative ease to increase the distance of the shot. Also, does the RP 20 take Micros or Megas in dart size?
