  • Trigger Upgrade Replacement Kit for the Ruger 77/22®

This sear and spring kit will make an amazing difference in the feel of your rifle's trigger. You'll have a clean break of around 1.5 - 2 pounds. Takes a few minutes to fit the sear to the rifle and you may have to do a bit of filing. Fits the Ruger®  77/22, 77/17, 77/40 and 77/50. 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.

What Is Trigger Pull weight?

Pull weight is the amount of force, 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.

    77/22 trigger upgrade

    Very simple process in replacing the sear and spring with the upgraded sear and spring. Just some minimal filing and polishing with some emery cloth on the trigger allowed smooth operation of the safety again.

    Timney's trigger upgrade is a quality product that was easy to install and functioned perfectly. I will be ordering more from Timney in the future.

    Timney 77/22 sear and spring

    Posted by James Patrick from Covington Kentucky on Jul 16th 2018

    Very easy to install. A lay person can do it. Just watch how it came apart. Just two pins to remove. I installed the new sear in no time at all but was dissatisfied with its performance. The pull had a hard spot in it before the brake and the trigger pull measured 2.98 lb. Spec’s on the pull was supposed to be between 1.5 – 2.0 lbs. I chatted with the Tec on Chat support and he advised to file or hone it down and that would resolve the problem. I ask for instructions and a diagram to do that but was told Timney didn’t have instructions for that. I was not happy with that because of my lack of knowledge on the procedure. I had no idea where to file. The Tec was very understanding and sent me a return form and even offered for me to send the whole rifle and they would tune up the complete trigger mechanism. In two weeks my sear was returned to me. The trigger now has a pull of 2.1 lb. and the pull is much smoother.
