The Timney Impact AR is a self-contained single-stage drop-in trigger with a curved shoe for AR-15 and M4 pattern rifles.
Timney quality at its most accessible — the Impact AR puts a clean single-stage drop-in trigger in every builder's reach.
The Timney Impact AR is the company's value single-stage: a fully self-contained drop-in module with a clean, consistent break through a traditional curved shoe. Built and tested to the same standards as Timney's flagship triggers, the Impact trades adjustability and exotic tuning — not quality — to reach its price.
Against a gritty, heavy factory trigger the difference is night and day: predictable take-up, a crisp break and a positive reset that make an ordinary rifle shoot like it cost more. For first builds and working rifles, the Impact AR is the smart entry into quality triggers.

Frequently Asked Questions
Which lowers does the Impact AR fit?
It is a drop-in unit for AR-15/M4 pattern lower receivers, supplied as a self-contained housing. Check your trigger pin size before ordering, as AR lowers are built in both small and large pin patterns. If the specification for your receiver isn't obvious, contact us with the make and model.
Where does the Impact sit in the Timney AR range?
The Impact is Timney's more affordable single-stage AR trigger, so it is the natural first upgrade from a standard trigger group rather than a full competition unit. You still get the single-stage break and drop-in cassette construction, without the price of the Competition or AR PRO models. It is finished in black and made in the USA.
Curved or straight shoe — what's the difference?
This is the curved shoe version, which mirrors the shape most shooters are used to and suits a conventional finger position on the grip. The straight shoe Impact is the same trigger with a flat bow, which some shooters find gives a more consistent contact point. Neither is better; it is down to how your hand sits on the rifle.
Is anything else needed to install it?
No, the cassette replaces your existing trigger group and uses the receiver's trigger and hammer pins. It is worth doing a careful function check once installed, and leaving anything beyond ordinary installation to a gunsmith.
