It's Nerf or Nothin! Standard Elite Nerf Dart. Regular weight is usually 1 gram and 1.3g for Steamline darts. Modeled this up after wanting some "gold" nerf darts. Adjusting infill can help get to an ideal firing weight. General function will vary on style of Nerf Gun due to how the darts are held in place. Open to adding more options if there is interest in the comments.
