The Timney Impact AR curved trigger (brand part number IMPACTAR) delivers a crisp, clean 3-pound break and drops into any mil-spec AR-15 lower without fitting. Every component rides captive inside a lightweight aluminum alloy housing, so the whole assembly installs as a single unit. The hammer is wire-EDM machined from S7 tool steel, chosen for a blend of hardness and impact resistance that resists chipping or breaking under heavy dry-fire and live use, while the remaining components are EDM cut from A2 tool steel and heat treated to Rc 56-60 for long service life. It installs using the rifle’s original hammer and trigger pins, and Timney’s proprietary design eliminates pin walkout.
