So that counts as a pistol even though it appears to have a rifle stock? Friend of mine has an AR pistol, I don't know much about them, but I had thought the legal issues amounted to barrel length and that it must have a short, fixed brace instead of an extendable rifle stock
In general, there are X number of things which make a rifle a rifle, and a pistol a pistol. Typically, an "arm brace" which this has, means that the weapon is allowed to be fired one-handed, and the barrel is shorter than 16 American inches (I say American inches because most other inches are used for dick size and ours are nominally smaller to make it so that we have larger gens).
The ATF released a paper in 2016 or 2017 saying "shouldering" an "arm brace" doesn't automatically make it a rifle.
Shouldering or not shouldering a weapon with an arm brace doesn't matter if there is a vertical foregrip, which is why there are so many angled foregrips.
The language is so specific it allows for more loopholes.
