WHAT DOES FRT FOR SALE MEAN?

I have tried using many diverse forced reset triggers, commencing with rare breeds authentic. When the ATF began knocking on doorways though, I disassembled it, grinded it up and tossed it from the trash as I didn't require any drama from a legally bought trigger. Anyhow, these triggers are wonderful. The FRT-L3 is the greatest I have used so far.R
