ARSS15 Forced Reset Trigger

Advanced Resting Safety System

BSsquirts X Gunetic

We are proud to introduce the ARSS15. This drop-in forced reset trigger fits AR-15 rifles. It reaches 700–900 rounds per minute while staying fully semi-automatic — both mechanically and legally.

Our team spent three intense months designing and testing it. We started with earlier open-source ideas. Then we set one clear goal: make the simplest, most reliable drop-in trigger possible. The result? Just four parts. Installation takes seconds. You need no modifications to the lower receiver. No filing, grinding, or fitting required.

Compatibility

• All mil-spec 90° selectors (standard 2- or 3-position KAK-style)
• M16 FA Ambi selectors (works with standard mil-spec triggers, single-stage triggers, or M16 fire-control groups)
• Geissele Automatics triggers — fully compatible when you install the Geissele Over Travel Device (OTD)
• Standard mil-spec or enhanced trigger pins
• Requires a full-auto profile bolt carrier group for proper function
• KAK 3 POS selector

Materials & Construction

• Reset lever and cam precision-machined from D2 tool steel using wire EDM
• Housing CNC-machined from 7075-T6 aluminum and hard-coat anodized
• Built and tested to survive long, high-rate firing sessions

How It Works

Here’s the cycle, step by step:

1. You pull the trigger rearward. This releases the hammer and fires the round — just like a normal semi-auto trigger.
2. Next, the bolt carrier moves rearward under gas pressure.
3. While it moves back, the underside of the full-auto profile carrier pushes down on the ARSS15 reset lever.
4. This motion travels through a simple cam. The cam then physically pushes the trigger forward into full reset.
5. At this point, the trigger is locked. It cannot move rearward again until the bolt returns fully forward and locks into battery.
6. Only after the bolt is locked and the disconnector hands the hammer back to the sear can you pull the trigger again.
7. If you keep steady rearward pressure on the trigger, it fires the instant the bolt locks. The cycle then repeats.

This required return-to-battery lock is the key feature. It guarantees one separate trigger pull for every round. That is why the ARSS15 remains a legal semi-automatic fire-control part under current ATF rules (November 2025).

Summary

In short, the ARSS15 gives you the fastest practical semi-auto rate on the market. It uses only four parts and has proven reliable over thousands of rounds. We still strongly suggest you get in installed by a certified quality gunsmith.
