It appears that the ATF with one fell swoop has reclassified millions of legally purchased weapons which were purchased as pistols to now being NFA short barrel rifles which requires registration. These weapons were sold as pistols. The weapons had an installed brace so that the gun could be held steady but yet not be shouldered. This is going to be a big cluster for anyone who owns those weapons. According to my limited research owners have several choices. Turn the gun into the ATF, remove the brace and render it so that it could never be installed again, or register it. They have given 120 day grace period for this to be done. I can't imagine they will be able to process the millions of requests for registration within 120 days.
