Review
Well the spring worked but my bolt is different than the one the worked on so couldn’t use the shims but I guess the springs ok
I just finished installation of the trigger spring/shim kit in my Ruger 77/357. It went very well. Trigger pull was reduced by about 40% and the shim took out the sloppiness in the bolt. I’m very pleased. Easy to do and highly recommend.
Fantastic product and service. It took me longer to clean my gun afterwards than to change the spring. Video couldn't have been simpler to follow. Looking forward to getting back out to try it out prior to whitetail season here in NC
The factory trigger pull was so bad on my 77/357. After putting in the new spring, it's still a bit more than I like but much lighter, and very predictable.
I am no gunsmith but by watching the how to video---I was able to install both the trigger spring and shim in about 15 minutes. I have no test equipment but by feel --I can tell a big difference in the trigger. With the shim the bolt works more solid. Great product and service.
Easy ordering, fast delivery, perfect fit. Video on website made installation a breeze. Very pleased.
Everything I have purchased from this company has been Q1 and precision fitting. The video's are done nicely as well.
Product arrived promptly and worked as advertised.
I've always liked the old Ruger M77 Rifles, except for the heavy triggers; now someone has FINALLY come up with a simple way to make the trigger pull reasonable, while still being safe. Easy to do, and makes the old gun shoot like new!
After reviewing the installation video, the installation process was quick, easy, and satisfactory. The trigger functioned better than some of the "custom" triggers I have on other rifles. I have already and will continue to recommend Mcarbo to my friends.
Trigger/sear spring worked pretty good in my Ruger Gunsite Scout Rifle. Installation was easy, installation video was outstanding. Pull wt. dropped from 3.75 to 2.0#, but I still need to do something about reducing the takeup. The shims aren't for the RGSR bolt, so it the cost of the kit makes for a pricy spring.
( History of rifle) Bought new in 1991, Ruger 77/22 in 22WMR, boat paddle stock, less than 150 rounds. Before installing the Mcarbo upgrade kit, (5) trigger pull average - 4.5 lbs. After trigger spring replacement, (5) pull average - 3.2lbs. As far as the shim kit is concerned, I originally installed the 0.2 shims only & it felt about the same to me. So I disassembled the bolt again & added the 0.1 shims also, & WOW, what a difference it made in solid lockup. I would have never thought with that few of rounds through the rifle that it could possibly need that much. The whole process took about 20 minutes, & is well worth the cost & time. Another great product from Mcarbo & the installation video is fantastic also. I highly recommend this kit & everything I’ve bought from Mcarbo to date. Thanks
Ordered two for my Ruger rifles, 270 and 30-06 calibers. Dropped both trigger pulls about 1 to 1-1/2 lbs and they both feel great. Definitely a must have upgrade. I have ordered other springs from MCarbo, the products are always well made and shipping is fast.
I installed this kit on an M77 mk2 that averaged 5 lb trigger pull. The install video was very detailed and step by step. After watching the video the install only took about 10 minutes. The result is a trigger pull that averages 3.5 lbs. Perfect for a hunting rifle and a fraction of the other aftermarket options available to improve these triggers.
This is my first attempt at “gunsmithing”. Very easy, as shown in video. Ruger Hawkeye FTW 6.5 Creedmoor. Went from 3.4 lbs to 2 lbs. Very satisfied.
Reduced my trigger pull from stock 5 lbs to 4 lbs on my M77 Mk II. Shims are not usable for the bolt on this model, didn't have any play anyway.
