ARC-Fire Trigger – Ambi Kit

The ARC-Fire Trigger Ambi Kit from AS Designs is an ambidextrous selector trigger system built around the patent-pending Active Reset Clutch (ARC). One of the most advanced kits in our super safety trigger range, the ARC-Fire forces the trigger to reset immediately after each shot for fast, precise follow-up shots, firing one round per action of the trigger while keeping the firearm semi-automatic. The kit includes the ARC components plus a pre-cut trigger and standard safety detent.

The ARC-Fire fires one round per trigger pull and keeps your firearm semi-automatic. Always confirm your state and local laws before purchase. You must be of legal age and eligible under federal, state, and local law to purchase.

Specifications and fitment

Ambidextrous, multi-platform design

The ARC-Fire uses a fully ambidextrous selector for fast access by right- and left-handed shooters, with three selector positions: Safe, Semi, and ARC. It is engineered to support more than ten widely used firearm platforms including AR-15 (.223/5.56, 300BO, 9mm, 10mm, .45, .40), MCX, MPX, MP5, G3/91, JAKL, Stribog, and Dissent. Several platforms require a platform-specific slip trip or lower kit, so check your platform before ordering.

Trigger compatibility

The ARC-Fire works with most mil-spec triggers that have a super-safety (SS) cut, plus many Geissele, ALG, BCM, PSA, Aero Precision, CMMG, and Anderson fire control groups with an SS cut. Some triggers (marked with an asterisk on the included list) need an additional lever-blocker part to prevent overtravel. Known incompatible triggers include the LaRue MBT-2S, CMC single-stage flat/curved, and Rise Armament RA-140. The cam, lever, and detent bar are M2 tool steel with a DLC coating, and the selector levers use a Black Oxide finish, the kind of quality you will find across the FRT triggers at FRT Triggers USA.
