This guide details how to ensure reliable operation of Rare Breed FRT (Force Reset Trigger) units, particularly when used with full-auto capable uppers like belt-fed or piston systems. Key steps include using blue Loctite on the selector lever and, crucially, replacing the standard buffer with an H3 buffer. The instructor emphasizes that the H3 buffer is the primary solution for common reliability issues encountered with FRTs.

Quick Summary

To ensure your Rare Breed FRT trigger operates reliably, especially with full-auto capable uppers, the key is to use an H3 buffer. This heavier buffer helps manage the bolt carrier group's cycling speed. Additionally, apply blue Loctite to the ambi selector lever components to prevent loosening.
