One of the Must Have Ruger 77/22 accessories that is worth every penny when you feel your New Ruger 77/22 Trigger. This is your Ruger 77 44 Trigger Job and your Ruger 77 22 Trigger Adjustment since these factory springs are the exact same in both Ruger 77 Rifles.
Ruger 77 Bolt Shims include 2x .001" and 2x .002" for a total of .006" potential adjustment. Most likely you won't use more than 2 of them but you can stack all 4 together if needed. The Bolt Shims will ensure the bolt is tight against the breech. As you've noticed, the bolt is in two major separate pieces. There is a bit of slop between the two parts due to natural manufacturing tolerances. As a way to ensure ultimate precision, we've developed this kit to assist you in ensuring that the 2 pieces of the bolt are tight against one another. The shims will also ensure that the bolt and breech are tight enough to prevent light strikes and misfires. The Ruger 77 Bolt Shims will not affect the actual head space as the head space is in the machined recessed face of the bolt.

Ruger 77-44
I watched the video & it showed a less than 2lb trigger pull!............. I installed my kit in my
77-44 today, had a 7 lb pull before,...... after I had a 5.3 lb Pull............. I gained less than
2 lbs, It was easy to install, but Not Worth the time & trouble for what little bit gained.
I purchased 2 packs had planned to do my 77-357 as well, Don't plan to use it, as its
Not worth taking it apart for the little improvement, plan to get a whole adj. trigger assemble.

ruger 77/22 triger kit

Sp101 spring kit
Installed this spring kit/polish on my DAO SP101 and wow 🤩 cut the trigger pull in half to 4 1/2 lbs. I highly recommend this for your Ruger revolvers
Ruger SP101
1st and foremost service is amazing!! On to the review. Video and instructions were flawless. Completed the change out and polish work in just over an hour, not a professional gunsmith here. The manufacturer trigger pull of over 12lb is gone. I can tell you it’s reduced to 5lbs or less, super smooth and was able to keep a tight group with 38 CCI and 357 FIOCCHI. This is my 3rd trigger upgrade from MCARBO and they have my utmost respect on their products and customer service! Great work Hoooyaaaaa!
Trigger return spring
The install was easy just like the instruction video outlined. My results weren't as favorable as the video, but I started with a heavier trigger pull. Overall ordering was easy, shipping was quick, install was as shown.
Works
Should have bought this before.
Simple and easy to install and does just what it’s supposed to do.
Would buy again
Ruger Mark ll
I bought the kit for my m77 22,17,and 22hornet. The first one was easy to install with video help. Then I installed the other two in about 20 minutes. Makes a world of difference in accuracy. Did realize how much I hated the factory trigger. Told all my friends about it. Thanks Dave
will this kit work in a Ruger M77 Mark II--. 223 caliber?
As long as your firearm does not have a tang safety, this kit will fit and function safely for your model!
I installed new trigger spring and .001 bolt shim. Put it back together and my trigger pull went from 4.8 lbs down to 3.55 lbs Was hopping for a lower trigger pull. Everything looks in place. Any suggestions?
We always recommend polishing up any contact surface areas to help smooth out the operation, this may help drop your trigger pull down a little further!
Will this spring kit work on a Ruger M77 in 280 Remington?
