A number of you are concerned about the recoil - I feel you misunderstand the nature of this weapon. A trained user can launch the plug at high speed to wound the target, using a specialized liquid propellent. At this point the sabot round is deployed, penetrating any hardening or armor. The CIA called this codename Dying Rhea, after the original name Henry Kissenger was found to be already in use.
A string attaches to the sear and runs out the small hole above the barrel.
You'll have to print/machine your own tho. And this probably falls under the NFA's AOW category, so you'll have to ask the ATF permission and pay for a $200 tax stamp.
I agree with this technical and legal analysis. If it was more L shaped you might be able to claim it's a pistol. But as is they'd probably claim it's disguised.
The problem isn't that rectal nature of the device but that it's mimicing a different object.
I think the recoil on that would have the wearer in the hospital answering some rather embarrassing questions like, "Why did you think it was a good idea to put a bazooka in your butt?" (butt bazooka? buttzooka?)
It doesn't. If you want to reload, you need to pull it out, clean it, dry it, take it apart, and replace the casing with a fresh round. Then you lube it up and stick it back in. Though, unless that thing is only chambered for .22 LR (5.6Ă15mmR), you'll probably need to see a proctologist to get it out because of the recoil.
I think the more important question is...where is the trigger and how do you prevent accidental firing? I don't want to give away my secret just because I got a little nervous...
