The CMC Triggers 92503 Drop-In Single-Stage Flat Trigger with 4-4.50 lbs Draw Weight & Black/Silver Finish delivers combat-ready reliability for AR-15/AR-10 platforms, featuring a straight, single-stage action that provides a crisp, fast lock time thanks to full-strength music wire springs and a high-grade 410 stainless steel housing. Engineered for minimal take-up and over-travel, this trigger is factory tuned for a 3.5 lb. or 4.5 lb. pull to suit precision or duty-style shooting, while installation remains fast and simple by inserting the one-piece assembly and using the supplied oversized pins. The trigger assembly is designed to fit mil-spec receivers with standard small pins and uses hammer, trigger, disconnector, and pins built from the highest-grade, hardest-wearing materials to maximize durability and performance under demanding conditions. With its Black/Silver finish, the 92503 Drop-In Trigger Kit integrates seamlessly into rifle builds, delivering a flat, clean break that enhances control and consistency across rapid-fire strings and precision shots alike, making it an excellent upgrade for shooters seeking dependable, factory-tuned pull weights without compromising reliability.
