Product description
The Timney Triggers Impact AR-ST Drop-In Trigger is a drop-in trigger designed for AR-15 rifle trigger operation.
This trigger features a 3 lb pull weight and uses billet machined components including heat-treated tool steel trigger and sear elements. The Timney Triggers Impact AR-ST Drop-In Trigger fits AR-15 style rifle models and is not compatible with AR-10 platforms. It is a self-contained unit with an aluminum housing that retains all internal components and installs using standard hammer and trigger pins. In standard configurations, the trigger maintains alignment within mil-spec lower receivers. This product is used for controlled trigger actuation in semi-automatic rifles and is categorized as a drop-in trigger system. The internal parts are heat treated for wear resistance, supporting long-term functional consistency in AR-15 builds.
