Q & A
What ammunition does it work best with?
In our testing, this trigger has run flawlessly with 115gr and 124gr FMJ range ammunition. We did note one hiccup during testing with a specific brand of 147gr subsonic rounds, so for optimal reliability, we recommend sticking with standard-pressure loads.
Is this a drop-in trigger?
Yes. The FRT-15L3™ (FLAT) is a self-contained drop-in unit. It comes with its own anti-rotation pins for installation into a standard AR-15 lower receiver. No additional parts are required.
What is the pull weight?
The pull weight is determined by the forced reset mechanism and is not adjustable in the traditional sense. The break is crisp, and the reset is very short and positive, which is characteristic of this trigger design.
