ATF overreach. What is a machine gun? Pull the trigger and hold it back and multiple rounds are ejected through the barrel. With an FRT the trigger must be pulled again for each round to be fired, thus not a machine gun.
The FRT is not an accessory that I would spend my money on, but that's just a personal opinion.
From bearingarms.com/john-petrolino/2022/03/25/atf-targets-triggers-plays-fast-and-loose-with-the-law-n56756#:~:text=As%20the%20name%20implies%2C%20Forced%20Reset%20Trigger%2C%20the,first%20without%20moving%20the%20trigger%20back%20and%20forth.
An explanation of the operational limits of an FRT
"The makers of the FRT were actually ingenious in both their design and naming of the trigger group. As the name implies, Forced Reset Trigger, the trigger assembly through the course of fire is forced to a reset potion, thus the trigger MUST travel rearward in order to fire again. The device is constructed to where it’s physically impossible to fire a subsequent shot after the first without moving the trigger back and forth. Thus, the ATF is grasping at straws to cram this round peg into a square hole. The actions needed do not fit the description outlined in the statute they cite: “…by a single function of the trigger.”
