Description

The Tac-Con 3MR Trigger System redefines AR-15 performance by combining match-grade precision with a patented assisted reset mechanism. Designed for enthusiasts and competitive shooters alike, this drop-in module delivers faster follow-up shots, enhanced shooter control, and lasting durability without sacrificing safety or legal compliance. Whether you’re upgrading a daily-use rifle or building a competition-ready AR-15, the 3MR provides a noticeable improvement in speed and accuracy.

Innovative Assisted Reset Mechanism

At the heart of the Tac-Con 3MR is its assisted reset technology. Unlike traditional triggers that rely solely on spring tension, the 3MR actively returns the trigger to reset position after each shot. This reduces reset distance by up to 60%, allowing shooters to maintain a smooth firing rhythm and tighter shot groups during rapid-fire scenarios. The tactile reset also provides immediate feedback, ensuring consistent shot placement and reduced shooter fatigue.

Three Distinct Operating Modes

The 3MR features a user-selectable safety selector offering Safe, Semi-Automatic, and 3rd-Mode operation. Safe mode fully disables the trigger for secure handling. Semi-Automatic mode fires one round per pull just like a factory trigger. The patented 3rd-Mode employs the assisted reset to achieve quicker follow-up shots while remaining within the legal definition of semi-automatic fire.

High-Grade Construction for Reliability

Crafted from aerospace-grade aluminum and hardened tool steel components, the Tac-Con 3MR Trigger System is built to withstand rigorous use. Precision machining and a durable finish resist wear, ensuring the trigger’s pull weight and reset remain consistent shot after shot. Each assembly undergoes strict quality control to guarantee smooth operation and long-term reliability under all shooting conditions.

Key Benefits

  • Speed: Achieve faster split-times with a significantly shorter reset and crisp break.
  • Control: Enjoy a clean trigger pull and positive tactile reset for superior accuracy.
  • Durability: Premium materials and craftsmanship provide lasting performance.
  • Compliance: Remains a legal semi-automatic upgrade in all jurisdictions.
  • Ease of Installation: Drop-in design requires only basic tools and minimal gunsmithing experience.

Easy Drop-In Installation

Installing the Tac-Con 3MR Trigger System is straightforward. After verifying the rifle is unloaded, remove your factory trigger group, insert the 3MR assembly, and secure with the supplied pins. No specialized jigs or proprietary tools are required. A simple function check ensures proper operation and safety selector alignment. Most users can complete installation in under 15 minutes.

Operation and Safety

Despite its advanced assisted reset capability, the 3MR maintains rigorous safety standards. The disconnector and safety selector prevent unintended discharge, and the trigger will not fire unless deliberately engaged. Shooters benefit from rapid semi-automatic fire while preserving full control over each shot.

Compatibility and Fit

The Tac-Con 3MR is designed as a direct replacement for most mil-spec AR-15 lower receivers. Tolerances are engineered to NATO specification, ensuring a snug, wobble-free fit in Colt, PSA, Aero Precision, and other standard lowers. Always verify compatibility with your specific lower receiver before purchase.

Comparison to Other Aftermarket Triggers

Compared to forced-reset designs, the Tac-Con 3MR offers a smoother, more controllable shooting experience. Unlike some rapid-fire triggers that rely on bolt carrier motion, the 3MR’s mechanical assistance provides consistent reset independent of carrier speed. Many users find the 3MR easier to master, with a more natural trigger feel and predictable performance.

Legal and Regulatory Compliance

The 3MR Trigger System complies with all federal regulations governing semi-automatic firearms. Its assisted reset does not convert the rifle into a fully automatic weapon, ensuring legal use in California, New York, New Jersey, and other states with restrictive laws. Always consult local regulations prior to installation.

Maintenance and Care

Routine maintenance involves light cleaning with a soft brush and solvent after each range session, followed by a thin coat of high-quality gun oil on moving parts. Periodic inspection of springs and pins ensures sustained performance. Avoid unauthorized modifications and adhere to manufacturer guidelines for best results.

Accessories and Upgrades

Enhance your 3MR installation with ambidextrous selectors, anti-walk trigger pins, and extended mag releases. For maximum reliability, pair with a quality bolt carrier group and recoil management system. Upgrades like competition springs and lightweight hammers can further refine trigger pull and lock time.

Customer Feedback and Performance

Shooter reviews consistently praise the Tac-Con 3MR for its transformative impact on split-times and shot accuracy. Competitive shooters report tightened groupings and higher scores in matches, while tactical operators value the blend of speed and control. The learning curve is minimal, and most users adapt quickly to leverage the trigger’s full potential.

Investment in Precision

Priced as a premium AR-15 accessory, the Tac-Con 3MR represents an investment in long-term performance. Its durable construction and proven design make it a standout choice for serious shooters seeking a competitive edge. Warranty support and direct manufacturer assistance ensure peace of mind with your purchase.

Conclusion

The Tac-Con 3MR Trigger System is a top-tier AR-15 upgrade for anyone demanding faster follow-up shots, unmatched control, and certified legal compliance. With its patented assisted reset, robust construction, and easy drop-in installation, the 3MR elevates the shooting experience across competition, tactical, and recreational applications.
