Well, for those of you wishing to pick up teeth... I have sad news... Whether or not this is allowed, I have created a flexible mouthpiece of rubber and vinyl, a "pre-barrel" longer then 9 inches to absorb all manner of mouth exhalations, a bolt action with consistent seating, and it shoots Nerf Darts. This may be disregarded here, but in my book, taking a week and being able to bring this from concept, to construction, to chaos, is a feather in my cap. I will post a video of it working when it's painted, for now I present it's photo album.
Questions or concerns can be ask at any point, and I will address them as I can.
