FRT Trigger FAQ

What is a forced reset trigger?

A forced reset trigger (FRT) is a semi-automatic trigger system that uses the firearm’s recoil and bolt carrier movement to mechanically force the trigger shoe forward after each shot. This creates an ultra-fast reset, letting you achieve high rates of fire by maintaining consistent forward finger pressure while still firing one round per distinct pull.

What was the first FRT trigger?

The Rare Breed FRT-15 was the original commercially successful forced reset trigger for the AR-15. The updated FRT-15L3 added a 3-position selector and further refinements for smoother operation.

How does an FRT differ from a binary trigger?

An FRT fires only on the pull with a forced forward reset. A binary trigger fires on both pull and release. Many shooters find FRTs offer more natural control and faster, more manageable splits for dynamic shooting.

Which platforms support FRT triggers?

AR-15: Excellent drop-in options including Rare Breed FRT-15L3, Partisan Disruptor, and selector systems.
Glock: Dedicated FRT kits for popular models.
MP5: Specialized forced reset systems. Heavy buffers (H2 or H3) and proper spring selection often optimize function, especially on shorter barrels or AR-9 builds.

What is the best FRT trigger ?

It depends on priorities:

Legacy performance and refinement → Rare Breed FRT-15L3
Best overall value and reliability → Partisan Disruptor (frequently praised in 2026 reviews for crisp reset at a strong price)
Maximum versatility → AS Designs Arc-Fire (pairs with your existing premium trigger)
