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

The Timney AR-15 Skeletonized 3 lb Trigger #661S with small pin is a precision aftermarket trigger assembly engineered for shooters who demand crisp, predictable break performance and reduced weight in their defensive rifle or competition build. Designed for AR-15 platforms utilizing small diameter pins, this trigger replaces the stock two-stage factory unit with a single-stage mechanism that delivers enhanced control and faster target transitions.

The 3 lb pull weight strikes the balance between safety margin and responsive shot execution that experienced operators and competitors expect. Timney's skeletonized design reduces reciprocating mass and contributes to overall weight reduction without compromising structural integrity or durability. The 3 lb trigger pull is achieved through optimized sear geometry and hammer engagement angles—eliminating pre-travel slack while maintaining clean, predictable break characteristics essential for accuracy under stress.

This trigger assembly is ideal for those running a duty rifle, tactical training setup, or precision competition platform. The small pin configuration ensures compatibility with most modern AR-15 lower receivers and operates smoothly through thousands of dry-fire and live-fire cycles. All surfaces are precision-machined from hardened steel, minimizing creep and overtravel, producing the consistent reset and cycling reliability that military and law enforcement professionals depend on in the field.
