CMC Triggers 47503 Drop-In Trigger Group 2.0 Single-Stage 3.5lb

The CMC Triggers 47503 Drop-In Trigger Group 2.0 transforms AR-15 performance with precision engineering that eliminates the creep and overtravel found in standard mil-spec triggers. This single-stage flat trigger delivers consistent 3.5-pound pull weight across thousands of rounds. The self-contained cassette design installs without gunsmithing or specialized tools.

What Makes This Different

Unlike traditional triggers that require individual component timing and adjustment, the Drop-In 2.0 arrives as a complete, pre-tuned assembly. The machined aluminum housing maintains precise tolerances that standard triggers cannot match due to receiver variations. CMC's proprietary sear geometry reduces friction by 40% compared to mil-spec components. The result is a trigger that breaks cleanly at exactly 3.5 pounds every time.

Key Features

• Self-contained drop-in cassette eliminates timing issues and reduces installation time to under 10 minutes
• CNC-machined 6061-T6 aluminum housing with blue anodized finish provides corrosion resistance
• Single-stage flat trigger face offers consistent finger placement and tactile feedback
• Precision-ground S7 tool steel hammer and trigger components rated for 100,000+ cycles
• Compatible with all AR-15 lower receivers including billet, forged, and polymer variants
• Anti-rotation pins included to prevent trigger movement during recoil
• Captured springs eliminate small parts loss during maintenance

Competitive shooters report improved split times and accuracy due to the predictable break and minimal reset distance. The 3.5-pound pull weight meets most match regulations while remaining suitable for tactical applications. Law enforcement agencies appreciate the reliability in adverse conditions, as the sealed housing prevents debris infiltration that can cause standard triggers to malfunction.
