People search these two together as if they were competitors. They are not — they are forced reset triggers for completely different guns. Here is the difference, and how to know which one you need.
The Rare Breed FRT-15 is an AR-15 trigger — it drops into the rifle's fire-control pocket and works with the bolt carrier. A Glock FRT is a pistol part — it replaces the Glock trigger shoe and fits a reset component to the trigger bar. Neither fits the other's gun. There is no adapter.
Both share the core concept: use the gun's cycling to force the trigger forward for a fast, one-shot-per-pull reset. But the AR version is a self-contained fire-control module, while the Glock version is a shoe-and-reset kit fitted to the existing trigger assembly. That changes how they install and how they are tuned.
It is decided entirely by the gun. Building or upgrading an AR-15? You are looking at an AR FRT like the FRT-15 or one of the other brands. Running a Glock? You need the pistol kit — our Glock FRT fits Gen 1–6 (excluding the Glock 44) and ships with both reset styles.
Both categories have been affected by federal FRT litigation. Confirm the current legal position and your state law before buying — see the legality guide.
No. The FRT-15 is an AR-15 trigger. A Glock needs a pistol-specific FRT kit that fits the Glock trigger bar.
No — same concept, different gun. The FRT-15 is for AR-15 rifles; the Glock FRT is a trigger-shoe kit for Glock pistols.
AR FRTs are closer to drop-in but sensitive to buffer/spring choice; the Glock FRT needs light fitting of the shoe and reset. Both reward careful installation.
