You asked, Timney listened. Introducing the Impact - the next trigger in the People’s Choice Line of Excellence from the craftsmen and women of The World's Finest Trigger.

All components are captive in the lightweight, aluminum alloy housing. Hammer is wire-EDM machined from S7 tool steel that combines hardness to resist wear with superior impact resistance to withstand heavy use without chipping or breaking. Other components are EDM cut from A2 tool steel, then heat treated to Rc 56-60 for long service life. Installs using your rifle’s original hammer/trigger pins, their proprietary design eliminates pin walkout.
