Introducing the AS Designs ARC-Fire – Active Reset Clutch Technology for Maximum Firepower

We’re proud to unveil the ARC-Fire, the latest innovation from AS Designs – a cutting-edge ambidextrous selector trigger system featuring our patent-pending Active Reset Clutch (ARC) technology. Designed to dramatically increase your firearm’s rate of fire without compromising control or compliance, the ARC-Fire forces the trigger to reset immediately after each shot, enabling rapid, precise follow-up shots – with one round per action of the trigger, every time.

Built for Speed. Designed for Control.
Multi-Platform Compatibility: Engineered to support over 10 of the most widely used firearm platforms, with more on the horizon. (AR15, JAKL, MP5, MCX, MPX, SCAR, BRN-180, G3, AP53, UMP, STRIBOG, DISSENT, and more to be added soon)

Ambidextrous Selector: Fully ambi design provides fast, intuitive access for both right- and left-handed shooters.

Three-Position Control: Selector positions include Safe, Semi, and ARC, putting enhanced speed and performance at your fingertips.

Reliable. Tactile. Responsive.
The ARC-Fire is built for shooters who demand performance and dependability. Our patent-pending design maximizes durability and reliability under sustained use. The selector switch is engineered for positive tactile feedback and effortless transitions – even under stress.

Go Faster. Stay in Control.
Whether you’re running drills, competing, or simply pushing your platform to its limits, the ARC-Fire delivers an unmatched blend of speed, precision, and durability – giving you the edge every time you pull the trigger.
