Tac-Con 3MR Trigger | 3-Mode Drop-In Trigger System for AR-15
Unlock next-level speed, precision, and control with the Tac-Con 3MR Trigger — a cutting-edge, drop-in trigger system engineered for serious shooters who demand more from their AR-15. Featuring a patented 3-mode selector, lightning-fast reset, and competition-grade performance, the 3MR (3rd Mode Reset) Trigger is built to dominate the range and deliver real-world reliability.
🔧 Product Overview
The Tac-Con 3MR (3rd Mode Reset) Trigger System is not your ordinary AR-15 upgrade — it’s a game-changing innovation that transforms your shooting experience with three distinct firing modes:
- Safe Mode – Standard safety, trigger disabled.
- Semi-Automatic Mode – Fires one round per trigger pull with a crisp break and reduced reset time.
- 3MR Mode (Assisted Reset) – Uses patented Positive Reset Assist Technology (PRAT) to mechanically drive the trigger forward immediately after a shot, enabling dramatically faster follow-up shots.
Unlike binary or forced-reset systems, the 3MR maintains full ATF compliance and functions within the limits of semi-automatic operation — but with the feel and performance of a high-end competition trigger.
