I understand that the Q,LLC owner is rightfully upset. However, he has grossly overstated the impact of the cease and desist letter set to Q. It did not make 4 million American felons. The letter applies only to pistols manufactured and sold by Q. It does not apply to all pistol braces manufactured by SB Tactical. I'm rather surprised that Colion seemed to accept this bogus claim, but perhaps he didn't want to contradict his guest.
This isn't to say that the BATFE won't go after other AR pistols with SB Tactical braces. They might do just that.
