The Timney Impact AR straight trigger (brand part number IMPACTARST) gives mil-spec AR-15 owners the same crisp, 3-pound Impact break as the curved version, built around a straight blade for shooters who prefer a flat trigger face. Every part rides captive inside a lightweight aluminum alloy housing, so the trigger drops in as a complete assembly without fitting. The hammer is wire-EDM machined from S7 tool steel for a mix of hardness and impact resistance, while the rest of the internals are EDM cut from A2 tool steel and heat treated to Rc 56-60 for a long service life. It reuses the rifle’s factory hammer and trigger pins, and Timney’s proprietary geometry is built to eliminate pin walkout.
