Description  more details

Self-contained module is ready to install in your small-pin AR and deliver an exceptionally smooth, crisp, creep-free single-stage trigger pull that feels more like a traditional bolt action than a combat rifle trigger. 100% drop-in—no gunsmithing, fitting, or adjusting required. 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. Precision-ground engagement surfaces ensure superb reliability and a crisp, clean hammer release. Installs using your rifle’s original hammer/trigger pins; proprietary design eliminates pin walkout. Available with standard solid trigger shoe with choice of 3 lb, 4 lb. or 4.5 lb. pull weight.

Since it was founded in 1946, Timney Triggers has built a reputation based on the quality of its products. Because of the precision machining and workmanship that goes into each Timney product they are The World's Finest Triggers.™ Each and every Timney Trigger is individually tested and calibrated by hand in the action it was designed for before it's delivered to the customer's door. 

Calvin Elite AR Lubrication:

To reduce friction add grease to the underside of the hook.

When installing your Timney Calvin Elite AR-15 trigger be sure to tighten down the set screws once the pins and safety are in place. No torque wrench is necessary, hand tightening should be sufficient.

AR rifle double fires:

AR doubling can be caused by several factors including incorrect installation procedure, disconnect distance being incorrect, or user error. If the trigger is installed correctly and the distance is correct the issue can be the response to recoil of the shooter. This is frequently an issue with prone shooting since it is more difficult to get a good tight shoulder weld on the stock due to the angle.

Timney’s AR line of triggers feature a very short reset. That short reset is critically important for fast follow up shots. A shooter can essentially relax a finger and the springs will guide the hammer to reset the trigger for the next shot. While this feature is a premier function of the AR trigger it is also a contributing factor in double fires if the shoulder is not snug to the stock during shooting.

The recoil pushes the stock into the shoulder, the shooter stays in the trigger squeeze through the shot, following through to the end of the range of motion. If the shoulder is not square and or snug so the recoil is properly absorbed by the body, the rifle will recoil forward from the shoulder and because the reset is so short the rifle will fire a second time. This is commonly referred to as a bump fire or bounce fire.

To prevent double firing be sure to keep the shoulder snug to the stock through the shot. If the rifle recoil causes it to bump off of the shoulder relax your finger so that you don’t inadvertently squeeze off a second shot.

Practice squeezing slowly and deliberately through the shot, squeeze the trigger until the range of motion has stopped. Once it is complete slowly relax the finger, listen and feel for the triggers reset. You will not need to pull the finger off the trigger but rather relax into the reset of the trigger. Once you have found the reset be sure to feel for it when shooting from other shooting positions, especially prone or from a bench/shooting stand.

I've Pulled A Lot..Of Triggers, and by Far for my DMR, There can be Only One.
I built an LR-308 and by the grace of God who loves Texans more than anyone, it has been the most accurate precision AR I've built. During the build, I had designated a 2 stage trigger because I like 2 stage triggers in my precision rifles and have an SSA-E in my SPR. But a very good friend of mine, SOF guy built a MK12 & had a skeletonized Timney in it. He swore by that trigger. Having spent years trusting his life to AR’s including precision AR’s in combat, his opinion was highly valued. So rather than go with the 2 stage per my build SOP for precision guns, I picked up a Timney. Zero grit, take up is like glass, break is crisper than a pita chip and reset is short and again like glass.  This trigger is a world class trigger. If I were going into combat with a DMR, I would want this trigger in it. Hands down, no compromise.

Colt LE6940 Information (Sear Blocks)
I have a good bit of long gun experience but not much with the Colt AR15's but hopefully this review will help other rookies like myself when trying to figure out if this Timney trigger 667S will fit in the Colts with a sear block. When searching the internet there is misleading and conflicting posts everywhere. I purchased a new Colt LE6940 this spring of 2017 and it has what is called an "integral" sear block where this Timney 667S trigger will fit. To my knowledge there are three types: (1) The earlier pre-ban models that do not have a sear block. (2) A type which has a pinned in sear block. (3) The present type that has the "integral" sear block where the metal has not been machined out. *The type 2 pinned in block will have to be removed in order for this 667S trigger to fit. 
Note: Timney customer service confirms the type 2 pinned in block will need to be machined out  for this 667S trigger to fit and they do offer the service.

Unreliable with Sig MCX new carriage assembly
My local gunsmith installed a Timney AR-15 Competition Trigger (4 lb, small pin, std curved) into my Sig MCX. While I love the feel and pull, I was getting light primer strikes with Hornady V-Max and other ammo.

It turns out that I originally had a Gen 1 bolt carrier group, which I sent to Sig to have it replaced with the Gen 2 version under the mandatory recall in Jan 2017. I didn’t purchase my Timney trigger through my gunsmith until Mar 2017. Unbeknownst to me, the Gen 2 bolt carrier group added a second spring on the firing pin. With this added tension, aftermarket triggers do not work properly, causing light primer strikes. Timney tech support says that as of June 2017 they don’t know of a solution but are working on one.

I didn’t realize that this trigger does not work reliably with my MCX and neither did my gunsmith. While the Timney web page says this trigger fits all mil-spec lowers, nowhere can I find a disclaimer not to use with the upgraded MCX bolt/carriage assembly.

Excellent customer service
I have had this trigger for about 5yrs now and the trigger seemed as if the pull got stiffer. I checked it with my Lyman digital gage and it read over 4lbs. I did all the directions via email and ended up sending it in, when I got it back within a week it read 2lbs 13oz. Excellent job. I received it completely rebuilt, it was in a package as if I bought a brand new trigger with the Timney sticker, allen wrench and set screws. Even the outside yellow paint with the Timney name look new, If I wasn't told it was rebuilt I would have thought they sent a brand new trigger. 

Excellent service and product. Their lifetime guarantee is just that with no fine print.

Thanks Timney!

What Is Trigger Pull weight?

Pull weight is the amount of pressure, in ounces or pounds, required to fire the trigger. Or in other words, how hard you have to squeeze the trigger to shoot your rifle. Timney Trigger experts at our Phoenix, Arizona plant hand-test every trigger in its intended action and then set the pull weight at our factory standard, 3 lbs.

If you prefer a different pull weight you simply select it from the drop down above and your Timney Trigger will be customized to your preference.

The #1 reason to replace your factory trigger with a Timney is accuracy. A lighter, crisper, more consistent trigger pull will make you more accurate with your firearm.

Below is a guide for pull weight selection:

2-2.5 pounds

Light trigger pull weights are great for people shooting lighter weight rifles as they can help keep you on target during the shot. Also common weights for target shooting from a bench.

3-3.5 pounds

By far the most common trigger pull weights -this is great for virtually all applications including target shooting, hunting and 3-gun competitions.

4.0 pounds+

Heavy trigger pull weights are good for cold weather hunting or applications where you may be shooting with gloves on.
