Short Barrel non NFA the new norm

[commando552]

On the topic of AR "pistols" does anyone have any crazy guesses about how the Franklin Armory Reformation is legal before it is unveiled at Shot Show? A lot of people think it is something to do with a binary (or related) trigger but supposedly this is not the case. My guess is that somehow that "stock" is not really a stock, like maybe it doesn't actually lock in the extended position or something like that.
