Rare Breed FRT-15L3® (MIL) — Mil-Spec AR-15 forced reset trigger
For shooters who want the traditional Mil-Spec selector and pin set, the Rare Breed FRT-15L3® (MIL) delivers single-stage forced reset performance in a familiar package. This drop-in 3-position FRT trigger (Safe / Semi / FRT®) is 100%% made and assembled in the USA — the authentic Mil-Spec forced reset trigger for sale, direct from Rare Breed Triggers.
How the forced reset trigger works
In FRT® mode, the FRT-15L3® (MIL) uses your firearm’s own cycling to drive the trigger forward into its reset position after every shot — so your next round is ready almost as soon as the gun is. The result is a dramatically faster, smoother and more consistent shooting cadence than a standard trigger. Crucially, it stays fully semi-automatic: the trigger fires one round per pull of the trigger, every time, and must fully reset before it can fire again. Want the details?

- Mil-Spec hammer & trigger pins included for a familiar, secure install.
