Timney AR-15 Skeletonized 3 lb Trigger #661S Small Pin

The Timney AR-15 Skeletonized 3 lb Trigger #661S with small pin is a true drop-in trigger assembly engineered for AR-15 platforms that demand precision and reliability. This single-stage trigger delivers a crisp 3-pound pull weight straight out of the box—no adjustments, no guesswork. Installation uses your rifle's original hammer and trigger pins, with Timney's proprietary design preventing pin rotation and walkout, a persistent problem with inferior trigger modules. Since 1946, Timney Manufacturing has built its reputation on precision machining and meticulous craftsmanship, positioning this trigger among the most respected options in the tactical and competitive shooting community.

The skeletonized design reduces overall trigger group weight while maintaining structural integrity and consistent trigger geometry. The 3-pound pull weight strikes a practical balance for patrol carbines and duty rifles—light enough to support precision work at distance, yet heavy enough to minimize accidental discharge risk during dynamic movement or stress scenarios. The small pin configuration ensures compatibility with standard AR-15 lower receivers. Timney's tight tolerances and quality control mean zero creep, consistent break, and repeatability across thousands of rounds—critical attributes for operators who rely on predictable trigger performance under pressure.

This trigger is built for serious shooters: law enforcement transitioning carbines to duty-grade ergonomics, competition shooters optimizing split times, and armed professionals who expect their equipment to function identically under all conditions. The drop-in installation means no gunsmithing, no specialized tools, and no downtime—a critical advantage during duty cycles or between training evolutions. The Timney #661S is a legitimate upgrade path for any operator running a stock trigger and seeking measurable improvement in control and shot placement without sacrificing safety margins.
