Frequently Asked Questions
Is this a true drop-in trigger?
Yes. The FRT-RD3™ (AMBI) is a self-contained cassette-style unit. It installs as a single assembly into a mil-spec AR-15 lower receiver without requiring individual pinning of the hammer and trigger.
Does it include anti-walk pins?
No, anti-walk pins are not included. The trigger is designed to function with standard mil-spec hammer and trigger pins. For added security during high-round-count use, aftermarket anti-walk pins can be installed.
Is the pull weight adjustable?
The trigger features adjustable pre-travel and overtravel, allowing you to fine-tune the take-up and reset. The main pull weight is set by the internal spring geometry and is not field-adjustable without changing springs.
