Timney AR-15 Single Stage Trigger 4 lb Small Pin Solid Shoe Curved

This Timney single-stage trigger is a self-contained drop-in module for AR-15 rifles that use the small-pin (original hammer and trigger pins) configuration. It is designed to deliver a smooth, crisp, creep-free pull with a single-stage feel. All components are captive within a lightweight aluminum alloy housing, and the trigger is supplied with a solid curved trigger shoe and a 4 lb pull weight.

The hammer is wire-EDM machined from S7 tool steel, chosen for wear resistance combined with impact toughness. The remaining internal parts are EDM cut from A2 tool steel and heat treated to Rc 56-60. Installation uses the rifle's original hammer and trigger pins, and the housing is designed to resist pin walkout. No gunsmithing, fitting, or adjustment is required. The trigger is semi-automatic and black in color.
