Because a standard AR pistol can't fire with the buffer tube folded, I'd think the measurement would be the end of the buffer tube.

But I'd still remove any VFG from an AR pistol with a folding buffer tube just in case (since common sense and ATF don't go together)

For pistol, as I understand, the ATF recently posted a letter stating the opposite for any PISTOL that has a brace. Must be measured collapsed (end of buffer) or folded (end of receiver/folding mount).
