Timney AR-15 Drop-In Skeletonized Trigger 4 lb. #664S - Small Pin

The Timney AR-15 Drop-In Skeletonized Trigger 4 lb. #664S with small pin is designed for shooters who require a crisp, predictable trigger break without the added weight or installation complexity of a full-profile unit. This trigger is ideal for law enforcement, competitive shooters, and tactical operators looking for enhanced performance.

The skeletonized design reduces reciprocating mass while ensuring reliability and precision. With a pull weight of 4 pounds, it strikes a balance between control and speed, making it suitable for both precision shooting and dynamic scenarios. The drop-in design allows for easy installation without modifications to the lower receiver, taking just minutes with basic tools.

This trigger is particularly beneficial for officers upgrading their duty rifles, as it offers reduced take-up and faster splits. Competitors will appreciate the minimal over-travel and clean break that enhances accuracy under pressure. The small-pin configuration (0.154") ensures compatibility with most modern AR-15 platforms.
