Flex3MR Assisted Reset Trigger for AR15 – AMBI

Description

The BFE Flex3MR Assisted Reset Trigger is a high-performance drop-in trigger system engineered for the AR15 platform. Designed to deliver a positive and rapid trigger reset for improved speed and control. Now featuring an upgraded ambidextrous safety selector, the Flex3MR offers enhanced ergonomics for both left- and right-handed shooters.

Built around a patented assisted reset mechanism, the Flex3MR Assisted Reset Trigger for AR15 uses the energy of the bolt carrier group to actively drive the trigger forward back to the sear, creating a distinct, tactile reset for faster, more consistent follow-up shots while maintaining a crisp, single-stage pull in both modes.

This trigger is CNC machined from high-strength materials and assembled as a self-contained cassette-style unit for simple drop-in installation into any mil-spec AR15 lower receiver.
