See the letter here:
The letter says the 60-day stay is to allow the Department of Justice to assess the applicability of National Firearms Act regulations to the Q’s Honey Badger pistol. Some will see this as a positive development. Maybe the regulatory giant is having second thoughts and the suspension gives them time to reassess.
A more cynical view would be the ATF has chosen to punt the decision until after the election to see which way the political winds are blowing when the 60 days are up in December.
If Trump is re-elected, the ATF might be persuaded of the arbitrary and capricious nature of their claim that the Honey Badger pistol is a short-barrel rifle and drop the matter. If Biden wins, they may decide that they were right all along in determining that the Honey Bader is somehow the equivalent of a SBR.
The ATF could then use their opaque, non-existent, non-standards which they refuse to explain or publish against other AR pistol/arm brace combinations, magically deeming them to be NFA items, too.
