CMC Triggers 90503 Drop-In Competition Single-Stage Flat 2.5lb AR-15

The CMC Triggers 90503 delivers precision competition performance with a crisp 2.5-pound single-stage break that eliminates creep and overtravel. This drop-in trigger assembly transforms standard AR-15 platforms into match-grade rifles capable of sub-MOA accuracy.

What Makes This Different

Unlike factory mil-spec triggers with their 5-7 pound pull weights and gritty breaks, the CMC 90503 features a machined flat trigger shoe that provides consistent finger placement and reduced perceived pull weight. The single-stage design breaks cleanly at exactly 2.5 pounds with zero creep, while the self-contained cassette design requires no gunsmithing or individual component timing. Installation takes minutes with basic tools, and the unit drops directly into any mil-spec lower receiver.

Key Features

• Precision-machined single-stage trigger with 2.5-pound pull weight
• Drop-in cassette design fits all mil-spec AR-15/AR-10 lower receivers
• Flat trigger shoe for consistent finger placement and improved control
• Self-contained unit eliminates timing issues and installation errors
• Hardened steel components with anti-walk pins included
• Competition-grade sear engagement surfaces for reliability
• Tool-free installation in standard trigger pocket

Competition shooters report immediate improvements in split times and accuracy due to the predictable break and minimal reset distance. The 2.5-pound pull weight sits in the optimal range for precision shooting while maintaining reliability for rapid-fire stages. The flat shoe design distributes pressure evenly across the finger pad, reducing the sensation of pull weight and improving trigger control during long strings of fire.
