Gun Control Reform Activism

You don't need the hypothetical of "rapid firing into one spot on a police officers bullet vest, to penetrate the vest" - even with the reduced energy of a short barrel, at any kind of reasonable shootout range, all commercially available .223 ammunition, utterly regardless of bullet design, is going to penetrate soft body armor with a single hit. It (the armor) is simply not designed nor marketed as any kind of proof against rifle fire; it's intended to stop lower-velocity larger-caliber pistol rounds and that's the long and the short of it.

That being said, I think any repeating rifle-caliber firearm with a barrel less than 16" should be immediately and retroactively classified as a Short-Barreled Rifle under the NFA regardless of the absence of a stock - that will meaningfully ensure the safety of law enforcement. I don't support the proposed restriction not out of any nuttery (frankly, SS109 is pretty crap ammo), but because it has absolutely no positive effect whatsoever on public safety (it might actually be negative, if people start to believe that soft armor is some magical proof against rifles), while whipping up the frothing "DEY TUK OUR GUNZ" crowd seemingly even more effectively than a proposed AWB.
