I have two SBRs, but there are millions of AR pistols in the wild. These new pending vague "rules" are clearly design to get all pistols registered as NFA items. ATF, in its generosity, has indicated that if you're the victim of a pre-existing felony (i.e., you own a pistol), you'll be able to register same and they will wave the $200 fee. "Guns and Gadgets" has an excellent video on YT. Going forward pistol sales will clearly be curtailed.
