Description
The Timney 667S-ST is a self-contained single-stage trigger module for small-pin AR-15 rifles. It replaces the factory trigger group as a complete unit with components captive in an aluminum alloy housing, and it is designed to deliver a smooth, crisp, creep-free pull.
The hammer is wire-EDM machined from S7 tool steel for hardness and impact resistance. The remaining components are cut from A2 tool steel and heat treated to Rc 56-60. The trigger is rated at a 3 lb pull weight and has a black and gold finish.
The module installs as a drop-in unit using the rifle's original hammer and trigger pins. No gunsmithing, fitting, or adjustment is required. It is intended for small-pin AR-15 platforms and is not designed to function in a polymer lower.
