Timney Impact AR Trigger

Newest AR Trigger from Timney

Timney was asked to come up with an AR trigger at a lower price point without sacrificing quality for budget-minded AR builders. With many of the same features as the flagship 667S, Timney would like to introduce the Impact AR trigger - the next trigger in the line of excellent triggers from the craftsmen and women of the world's finest trigger

Timney's engineers figured out a way to machine the parts from billet steel (no skimping with metal injection molding or stamped old-school parts), assemble the triggers, and still hand-test this trigger by our trigger technicians at a price that you asked for - $149.99. The Impact will give you a crisp, clean, 3 to 4 pound-range break and will drop into all Mil-Spec AR’s.

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, our proprietary design eliminates pin walkout.

The secret to long-range accuracy? It all starts with an amazing trigger and this trigger, is truly amazing. The new Impact trigger is Timney’s latest overnight success – 73 years in the making.

Timney Triggers is dedicated to ensuring our customers a lifetime of hassle-free shooting enjoyment. In the last step of the manufacturing process, each trigger is hand-assembled, tested, and calibrated for the specific rifle model it is intended for before it’s delivered to the customer’s door.  Timney Triggers is proud to offer a lifetime warranty on all of its products and each trigger is proudly Made in the USA.

Please Note: The Impact is not compatible with the AR-10.
