It states pretty clearly on page 162 that an AR with a functional carbine length buffer tube cannot be considered a stock.
One objective design feature ATF may consider is whether the attachment is required for the cycle of operations of the weapon, which could indicate the firearmis not designed and intended to be fired from the shoulder. For example, an AR-type pistol with a standard 6- to 6-1/2-inch buffer tube may not be designed, made, and intended to be fired from the shoulder even if the buffer tube provides surface area that allows the firearm to be shoulder fired. On an AR-type pistol, the buffer tube encases a spring that drives the bolt forward when the bolt is driven into the buffer tube by the gas from the initial shot. The picture below displays the internal function of an AR-15 type rifle. The AR-type pistol is a variant of the rifle with the stock removed and has the same receiver and buffer tube function of the rifle version.
