Forced Reset Trigger Technology

The FRT-15L3 uses forced reset technology to eliminate manual trigger reset between shots, allowing significantly faster firing rates while maintaining one trigger pull per round. When the bolt carrier moves rearward after firing, the hammer cocks and contacts the trigger, forcing it to reset. A locking lever prevents the trigger from being pressed again until the bolt cycles. This creates faster follow-up shots than standard semi-automatic triggers without crossing into full-automatic operation. The three-position selector allows safe, traditional semi-automatic, and forced reset modes depending on the shooting application.

Adaptive Tactical EX Performance Stock

The Adaptive Tactical EX Performance stock uses glass-filled polymer construction for durability with reduced weight compared to aluminum stocks. The rubberized buttpad improves recoil absorption and provides a secure shoulder interface during rapid fire sequences. QD sling mount compatibility allows quick attachment and detachment of modern sling systems, while an integrated sling loop accommodates traditional sling configurations. The adjustable design allows length of pull customization via the 6 position carbine buffer tube, accommodating different shooter sizes, body armor, or shooting positions.

Ambidextrous Control Integration

The lower receiver features a milled ambidextrous bolt catch slot paired with an ambidextrous bolt catch kit, providing bolt lock and release capability from either side of the receiver. The 3 position ambidextrous safety selector completes the control package, eliminating the need to shift grip or break shooting position when operating the firearm from either shoulder. These features improve manipulation speed and flexibility for tactical applications, competition shooting, or training scenarios requiring weapon transitions.
