Nerf Sledgefire Mega Dart Shell

thingiverse

This shell lets you fire Mega Darts from your Sledgefire by loading them into the front first. The good thing about this design is that it doesn't require any modifications to your blaster, which is a costly piece of equipment now. However, the downside is that you can't load darts into the shell before hand. You have to put the shell in place, then attach a dart to the front. I've tried out this design and found that the Mega Dart doesn't travel nearly as far as those in the standard 3-shot shell. The dart fits tightly onto the front cylinder, while the shell sits perfectly inside the blaster. I think the problem may be due to air escaping through the gaps between the layers. If someone else can figure out how to fix this issue, I would really appreciate it.
