OK, it doesn't make your NERF gun quieter but it does look really cool. It has an extremely large bore so it will not affect range or accuracy. It was tested on both the CS-6 and STRYFE but should work on other models. I Designed it to lock onto the gun the same way as the "factory" extensions. The barrel is in two pieces so the tip can be printed in orange for safety. The small round piece with the bump on it is what secures it to the gun. If it wears down or breaks it can be easily replaced/reprinted without having to reprint the whole barrel. Feel free to remix this I would love to see them.
