What makes this cost twice as much as the other CMC single stage flat trigger? Also, what's up with "full auto" in the name of this trigger?

Doug, guest, from KS, United States, asked on November 23, 2024

What is difference between a full auto lower and a non full auto lower? Other than an auto sear in the trigger group. What is different between them?

Answered by Freedom Warrior, guest, from TN, United States, on April 30, 2025

The fire control pocket is dimensionally different in a full auto lower receiver to allow it to accommodate the auto sear, along with the additional hole for the auto sear pin.
