Seems like 3MR paid the right people.In regards to the question, did he get ATF approval? He didn’t, but Tac Con did when they released the 3MR in 2013. 3MR stands for third mode reset.
He included the ATFs letter to Tac Con in his complaint. The triggers do the same thing. They reset themselves. The 3MR trigger has been in the market for almost 8 years.
