Yes the FRT which is SIMPLY THE OPINION of the horse cops was illegally changed from NR to prohib. HOWEVER the OIC which IS THE LAW does not list any of the Modern line of rifles manufactured by ATRS, so in fact it could make a difference.
So what would happen if you take a MS to the range? I never got to even break my barrel in yet due to covid shutting down ranges till recently. I still have the original FRT from atrs.
