Frequently Asked Questions

What makes the Rare Breed FRT-15 trigger unique?

The FRT-15 is a forced reset trigger that uses the bolt carrier group's energy to reset the trigger. This allows for a very high rate of semi-automatic fire, as the trigger resets during the bolt's forward travel, enabling successive shots with minimal delay.

Is the FRT-15 trigger legal?

As of the video's recording date, the FRT-15 was considered legal and non-NFA. It functions as a semi-automatic trigger under ATF definitions, requiring one pull for each shot fired, despite its high rate of fire capability.

What firearms are compatible with the FRT-15?

The FRT-15 is designed for compatibility with standard AR-15 platforms. It has also been tested and shown to function with HK416 platforms, though specific hammer height considerations may apply for optimal performance.

What are the risks associated with high-rate-of-fire triggers like the FRT-15?

A significant risk is the potential for 'cook-offs' in closed-bolt systems due to extreme chamber heat. It's crucial to allow the firearm to cool and lock the bolt back after sustained rapid fire to prevent accidental discharge.
