Royal Nonesuch speaks on it:

0:10 – Talking about putting together a 12 GA slam fire tennis ball launcher / can launcher.  Sounds cool to me.  He’s kind of worried about ATF rules though so is going to do more research.  Ya who knows.  What’s perfectly legal this week, all of the sudden is all up in the air the next week.

2:09 – hahah I love the sketch.  “Grape Drink” LOL.

2:31 – If I had to guess, I bet the ATF is worried about people taking an empty can with no lid and stuffing flechettes or other random crap in it, then firing it out of the can cannon.

4:01 – He’s going to use a sliding rotating locking barrel for his homemade .50 BMG, since the keys failed in the previous video.

4:30 – Mark Serbu from Serbu firearms invited Royal Nonesuch to visit his facilities in Florida and build a gun down there using their equipment.  Wow sounds exciting.

Royal is wearing the Brass Bandit t-shirt from ENDO Apparel.
