Information

AS Designs ARC-Fire™ Ambidextrous Selector Trigger System (ARC Technology)

Reset Redefined. Patent-pending Active Reset Clutch (ARC) technology for faster trigger reset, improved control, and multi-platform compatibility.

The AS Designs ARC-Fire™ is a next-generation ambidextrous selector trigger system featuring patent-pending Active Reset Clutch (ARC) technology. Designed to enhance trigger reset speed while maintaining control and compliance, the ARC-Fire forces a positive, immediate reset after each shot—enabling rapid, precise follow-up shots with one round per trigger action, every time. Available at NSPEC Innovations.

Key Highlights

  • Patent-pending ARC Technology: Forces immediate trigger reset after each shot for faster follow-up shots.
  • Ambidextrous Selector: Fast, intuitive access for both right- and left-handed shooters.
  • Three-Position Control: Safe / Semi / ARC mode for quick transitions and adaptable performance.
  • Precision Materials: Tool-steel internals and 4140 steel selectors for durability under sustained use.
  • Multi-Platform Compatibility: Supports numerous popular platforms with additional kits where required.

How ARC-Fire Works

Customer video review of AS Designs ARC Fire Trigger | AR-15 Forced Reset Trigger | Ambi Safety

Super easy to install, runs smooth and without failure in a completely stock $500 American tactical AR, there are plenty of videos showing how to install it. Would and am buying this trigger kit again, and pairing it with a lighter spring kit, there isn’t any weird quirks with it, I simply installed it with some oil and my factory pins and springs and it worked without polishing or any other modifications. Super happy with it!

Try adding instructions or a link to your site with a tutorial for this in the package. I know it's on u-tube but you are the creators and I am not sure about the advice that does not come from the mfg. I went to the range this morning after the install. It went into and Anderson Multi - Cal using your trigger, my hammer. The uppers were BCA- .22LR/.5.56 and only ran once with the 5.56 set up, but only once firing about 5-6 rds. twice. I don't get it...can you advise me on this? Jack W. Las Vegas

BEWARE. probably the WORST communication I e EVER had to deal with. their voice mailbox is completely FULL and they do not answer ever. then once they do email you weeks after cancelling your order they only give you a partial refund if any. if you can find any of the products they offer on other sites I would deal with ANY other business over this company.

Installed 6 of these so far. After a steep learning curve, I figured it out. Before purchasing understand you need a full auto BCG, an H3 buffer, and not all lowers are compatible without modification!! Watch videos!!! They function well!
