BS Squirts ARSS15 Drop In - Forced Reset Trigger Kit - 9MM KIT

The ARSS15 is a four-part drop-in forced reset trigger (FRT) system designed for AR-15 platforms. It delivers high semi-automatic rates of fire (typically 700–900 RPM) while maintaining full mechanical and legal semi-auto functionality through a return-to-battery lockout. It requires no permanent modifications to the lower receiver.

The system uses a mechanical lockout that forces the trigger to reset only after the bolt fully locks, making it reliable and straightforward. It’s made from high-quality steel and aluminum parts, installs in seconds, and works with most standard mil-spec triggers and full-auto profile bolt carriers.

IMPORTANT NOTES:

• Includes

  • Premium Black Nitride 9MM Bolt Carrier Group - WEIGHT IS ALREADY CUT FOR FRT APPLICATIONS

    Most forced reset triggers have a small protruding lever, arm, or "sear trip" on the trigger that extends upward into the BCG area. This lever uses the rearward movement of the BCG to mechanically force the trigger forward (reset it) after each shot, enabling the rapid follow-up shots that make an FRT work.
     
    In a standard semi-auto AR-15 BCG, there is usually enough open space or a proper "full-auto" style tail. In many 9mm AR-9 BCGs, the rear interior of the carrier contains a heavy tungsten or steel weight (added for reliable blowback cycling in pistol-caliber blowback systems). This weight often sits right where the FRT reset lever needs to move freely. If the weight blocks the lever, the FRT won't reset properly — or worse, the upper and lower receivers may not even close all the way together.
