Timney Triggers 667-S AR-15/AR-10 Trigger

Timney Triggers supports the NRA to protect our rights. We like that!

Quick Q&A for the impatient:

  • How does the Timney Competition AR Trigger compare to other AR triggers? (The Timney is at the hard-core competition trigger end of the spectrum)
  • Is the Timney 667-S AR Trigger a good value at an MSRP of $229? (The price of the Timney is in line with other high-end options in the competition trigger market. Value depends on how well the drop-in, set pull weight trigger meets your needs.)
  • Should I buy a Timney Small Pin Competition AR Trigger? (The Timney is a great trigger at a fair price. Buy it if you want a fast action shooting trigger that is pre-assembled and has a set pull weight)
  • Is the Timney Trigger good for hunting? (We would consider hunting with the Timney if we were in a fixed position, like a deer stand)
  • Is the Timney drop-in AR Trigger a good upgrade for my duty rifle? (We prefer a trigger with a bit of creep and heavier pull weight for a duty application)

Bench testing

1) Assembly

We received the Timney Competition AR Trigger directly from Timney Triggers as a review sample. Josejuan installed the Timney Trigger in an otherwise complete AR-15 lower receiver provided by Anderson Manufacturing (Model AM-15). You can watch the installation video and read about the installation here:

In short, the drop-in module is a pretty simple installation that even a novice should be able to complete. However, it can be tricky holding the spring legs away from the screw holes to install the set screws. It helps a LOT to mount the lower receiver on a magazine well vise block to hold it completely still during the installation and free up both hands. *If you will if install in a polymer lower, then you should be aware there is also a warning in the instructions to use a small aluminum plate in the mag well. You need to request the aluminum plate when you order the trigger. We installed in an aluminum Anderson AM-15 receiver, so this was not an issue for us.

2) Hammer drop block

We started with the hammer drop block in the Timney Competition AR Trigger lower receiver to test the Timney trigger for proper operation and to get our heads around the trigger’s feel. This was an important step for us, as it allowed each of our 4 testers to rapidly switch the hammer drop block to different lowers and test the trigger feel for accurate comparison. We expected the  Timney Competition AR Trigger to feel like a 3 Gun competition trigger with a very light pull. The break was crisp on the hammer drop block, with a very short pull and reset.

3) Trigger pull scale

G.P.S. Trigger pull ScaleMeasuring trigger pull weight is pretty simple:

  1. clamp the magazine well block in the vise,
  2. slide the upper onto the magazine well block. So, the upper is completely stable and not subject to movement during trigger testing,
  3. cock the hammer by hand,
  4. reset the peak weight ring on the trigger pull scale,
  5. place the trigger pull scale test arm on the trigger in the location that you will place your finger when shooting,
  6. pull gently aft on the trigger pull scale until the trigger releases,
  7. record the peak weight from the trigger pull scale
  8. lather, rinse, repeat 2 more times
  9. average the 3 pull weights

The Timney Competition AR single stage trigger delivered trigger pulls of 4.25 Lb, 3.5 Lb, and 4.25 Lb for an average of 4.08 Lb.

Wait, what?

I thought the Model 667-S was pre-set at 3 LB?!

Maybe it will get lighter with continued use. We have to admit that it was such a short, smooth pull that it was hard to tell the weight by finger alone.  In fact, some of our testers commented on how light the trigger felt. However, this was in the ballpark for the more expensive triggers in the test; heavier than some but much lighter than a mil-spec trigger.  Some shooters noted that it would not be a good fit for a duty rifle, where too light a trigger can be a disadvantage/safety issue.

The Timney trigger was very smooth and crisp, with a short and distinct reset.   It inspired confidence.

4) Creep & Overtravel

I measured total travel the tip of the trigger at about 1/16 of an inch. There is nearly undetectable creep, and slightly less than 1/16″ of overtravel and reset. This makes the Timney Competition AR Trigger just about the shortest trigger pull and reset of all triggers we tested. This is great for the intended purpose as a fast action shooting competition trigger.

The Results

Group 1 shooting while our RSOs ensured range safety

100 yards

All 5 shooters slung five rounds of American Eagle 55 grain .223 Remington at small numbered paper targets from benches with shooting rests or sandbags at 100 yards to get a feel for how the Timney Competition AR Trigger performed under slow, controlled fire. The feedback was nearly unanimous that the Timney trigger performed in league with the best triggers in the test, with our most experienced Timney loyalist complaining that it didn’t live up to the standards of Timeny’s bolt gun triggers for slow, precision shooting.

 Short range tactical carbine

Chris from Three Pillars Shooting, LLC and Bob, our other NRA instructor collaborated to run the team through basic 3-10 yard quick target acquisition, rapid shot strings and short mag shoot-reload-shoot drills. In this scenario the Timney Competition AR Trigger performed very well, with a great balance between trigger pull weight and a solid trigger feel. Some of the competition triggers felt a bit light in this shooting scenario.  The Timney’s four pound pull weight felt well-balanced between speed and security.

AR15 trigger upgrade test Plate Rack duel40 yard plate rack

A 2 shooter duel to see who could hit the most of the 6 plates of 8 inch diameter in a horizontal row at 40 yards. The Timney trigger put in a respectable showing in the plate rack duels, but didn’t feel as fast as the best of the light, short-reset competition triggers. While much better than the mil-spec triggers, the Timney 667-S AR Trigger was reported to feel not quite as fast as the very best in the group. We will have more on trigger speed in our full Big Trigger Upgrade Test review coming soon. The results surprised some of the testers.

40 yard steel silhouettes

This was less formal with 2 shooters competing to see who could put a string of shots on their steel silhouettes most rapidly from 40  yards. We found that the competition triggers excelled with their ultralight trigger pulls and short resets. As with the 40 yard plate rack duels, the Timney Competition AR Trigger felt smooth and solid, inspiring confidence, but also felt just a bit slower than the best triggers in the test.

The Timney trigger was fun to shoot.  Most of the testers really liked it and no one disliked it.  Jason, a big Timney fan, initially felt it was not up to the standard of Timney triggers in his bolt-action rifles. However, after the Action Shooting portions of the test, he reported that he favored it as well. He still reported liking the JP roller trigger and Hiperfire 24C trigger better than this Timney trigger. Somewhat of a mixed bag. In my opinion, this is a rather nice competition trigger that was simply overshadowed in this test by two triggers that have innovative finger contact surfaces. I am actually leaning towards keeping the Timney Trigger in one of my personal lowers. I am looking forward to shooting this trigger more as it kind of grew on me during the final stages of testing… the plate rack and silhouette duels.

Gear Score
Excellent upgrade option for 3Gun and action shooting competitors that want an easy drop-in, set pull weight trigger

One of the first things you notice on the Timney Triggers website (timneytriggers.com) is that they are “Proudly made in the USA since 1946.” We certainly appreciate keeping the level of expertise developed over six decades of precision trigger work right here in the US of A. Timney has a significantly broader trigger catalog than any other manufacturer in our AR Trigger Upgrade Test, boasting 170 different trigger models for a variety of types of firearms and archery.

The Big AR Trigger Upgrade Test

We tested 9 AR platform trigger upgrades from 5 different manufacturers to identify:

  • Which AR trigger upgrade is the best value?
  • Which AR-15 and AR-10 triggers are best suited for hunting, competitive shooting, personal defense, duty rifle?
  • Which AR trigger do we like best?

Starting with a just barely broken-in “mil-spec” trigger group as our “control”, our team of 5 testers assembled and dry fired each AR FCG on the hammer drop block to get a feel for each trigger, measured trigger pull weight with a trigger pull gauge, then shot each trigger in long range, tactical carbine, and competitive shooting situations to assess each fire control group in a real-world setting. We shot nearly 2,000 rounds down a combined 6 AR uppers so we could provide the most comprehensive trigger upgrade review possible.

Huge thanks to Ammunition Supply Company, who kicked in 2,000 rounds of bulk 55 grain ammo for this test.
