This video provides an expert-level review of the Rare Breed Triggers FRT-15, a forced reset trigger for AR-15 and HK416 platforms. Instructors Mike Jones and John Crump detail its mechanics, legal status, and performance capabilities, including its potential for an Infantry Automatic Rifle (IAR) role. They emphasize its ability to achieve a high rate of fire while remaining semi-automatic by ATF definition and discuss compatibility with various upper receivers and the impact of gassing systems. The review also includes crucial safety warnings regarding heat buildup and cook-offs in closed-bolt systems.

Quick Summary

The Rare Breed Triggers FRT-15 is a legal semi-automatic trigger that achieves a high rate of fire by using the bolt carrier group's energy to reset the trigger. Unlike standard triggers, it physically forces the trigger forward, allowing for rapid follow-up shots. However, users must be aware of potential heat buildup and 'cook-off' risks in closed-bolt systems during sustained rapid fire.

Frequently Asked Questions

What makes the Rare Breed Triggers FRT-15 legal as a semi-automatic trigger?

The FRT-15 is legal because it functions as a semi-automatic by ATF definition: one round is fired per distinct trigger pull. The trigger mechanism uses the bolt carrier group's energy to reset itself, allowing for a rapid follow-up shot, but the user must still physically manipulate the trigger for each round.

How does the forced reset mechanism of the FRT-15 differ from a standard trigger?

A standard trigger resets via spring pressure after the hammer falls. The FRT-15, however, uses the rearward and forward movement of the bolt carrier group to physically push the trigger back into the reset position, enabling a much faster rate of fire.

What are the potential risks of using a forced reset trigger like the FRT-15?

The primary risk is excessive heat buildup in closed-bolt firearms during sustained rapid fire, which can lead to 'cook-offs' where rounds ignite in the chamber without a live primer. It's crucial to lock the bolt back to cool the firearm.

Which AR-15 upper receiver configurations work best with the FRT-15?

The FRT-15 generally performs more reliably with over-gassed systems. Testing with various uppers, including military-gassed MK18 Mod 1 and standard M16 uppers, showed performance variations dependent on the rifle's gassing. Budget Aero Precision uppers were also tested.
