What you get
- Tac Con 3MR Trigger assembly with proprietary reset mechanism

- Tested to 50,000+ rounds in stress testing
Build and finish
The 3MR’s hammer and trigger are CNC-machined from 8620 alloy steel, heat-treated to RC 45-50 for durability under rapid fire. Unlike polymer-housed binary triggers, the all-metal construction withstands carbon buildup and maintains consistent performance in dusty or wet conditions.
Nickel-boron plating reduces friction while resisting corrosion, a critical feature for suppressors or high-volume shooters. The sear engagement surfaces are hand-lapped to 0.0005″ tolerances, eliminating creep without requiring aftermarket polishing.
Compatible platforms
- AR-15/M4 pattern rifles (5.56/.223)
- AR-9 PCC variants with mil-spec trigger pockets
- AR-10/LR-308 models (requires verification of trigger pocket dimensions)
Installation notes
Installs like any mil-spec trigger group using existing pins. The 3MR requires no special springs or tools, but we recommend checking hammer clearance with aftermarket bolt carriers. Includes detailed instructions for adjusting reset tension to match your shooting style.
For hunters and competitive shooters who demand mechanical reliability with near-binary speed, the Tac Con 3MR bridges the gap between traditional triggers and electronic systems. Available exclusively through authorized dealers like Conway Hunting Supply, this U.S.-made trigger ships with a lifetime warranty against defects.
