Description

The Timney Impact AR Trigger takes one of the most common complaints about a factory AR-15, that heavy, gritty stock trigger, and fixes it in about the time it takes to drink a cup of coffee. It's a self-contained, cassette-style unit that drops right into most mil-spec AR-15 lowers and uses the original hammer and trigger pins. Timney gauges the pull between 3 and 4 pounds, and folks who've run it describe a crisp break with minimal creep and a short, snappy reset. It's a single-stage design, so there's no take-up before the wall, just a clean release.

What Sets the Impact AR Apart

Timney machines the internals from real steel instead of stamped or injection-molded parts. The hammer is wire-EDM cut from S7 tool steel, which shrugs off the repeated pounding an AR hammer takes, and the other components are cut from A2 tool steel and heat treated to Rc 56-60 for a long service life. Everything stays captive inside a lightweight 6061-T6 aluminum housing, so no small springs or pins go flying when you swap it in. The curved trigger bow gives you a natural, familiar finger placement.

Installing the Timney Impact

This is genuinely a drop-in job. You pull the grip, safety, and old trigger, set the Impact housing in place, and reinstall your pins. Timney's proprietary set-screw design locks against pin walkout, so anti-walk pins aren't required, though plenty of builders like to add them since the pins are already out. One tip from the field: you'll need to move the hammer spring legs aside to reach the set screws, then reposition them once the housing is seated. Most people have it done in 15 minutes with simple hand tools.

Where the Impact AR Fits

This is the small-pin (.154 inch) version built for standard mil-spec AR-15 lowers. It's a smart upgrade for range guns, hunting builds, and general-purpose ARs where you want a big jump in trigger feel without a lot of fuss. Note that it's made for the AR-15 platform and is not designed for AR-10, 15-22, or 7.62×39 rifles. Made in the USA and backed by Timney's lifetime warranty.

Frequently Asked Questions

Will the Timney Impact AR Trigger fit my AR-15?

It's built for mil-spec AR-15 lowers using the small pin (.154 inch) footprint, which covers the large majority of AR-15 rifles out there. It is not designed for AR-10, 15-22, or 7.62×39 platforms, and it won't work with large-pin lowers that use .168 to .174 inch pins. If your rifle takes standard small pins, you're good to go.

Do I need anti-walk pins with the Impact AR Trigger?

No. Timney's proprietary set-screw design locks the housing against the pins to eliminate walkout, so you can install it with your rifle's original hammer and trigger pins. That said, since the pins are already out during install, some builders choose to add a set of anti-walk pins for a little extra peace of mind.

Is the Timney Impact single stage or two stage?

It's a single-stage trigger, meaning there's no take-up before the break. You get a clean wall and a crisp release right where you expect it. Timney sets the pull between 3 and 4 pounds at the factory, and it is not adjustable.

How hard is the Impact AR to install?

This is a true drop-in job that most people finish in about 15 minutes with basic hand tools. You remove the grip, safety, and old trigger, seat the self-contained housing, and reinstall the pins. The one thing to watch is moving the hammer spring legs aside to reach the set screws, then repositioning them once the unit is seated.
