So I posted Clint Westwood’s DIY video of how he rifled a barrel. Then I wondered what he was rifling a barrel for. Well he converted a staple gun to fire .410 shotgun shells.

Since this is a rifled .410, does this fall under law as a pistol? Or AOW? It is not a SBS since it was never designed to be fired from the shoulder.

Here is the prototype. A single shot version that fires .410 shells.

Here is the assembly of the final product. In this video, the creator explains that he was trying to make this resemble a caulking gun.
