Review
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
I was looking for springs to soften up my sp101 trigger. I found this kit with shims making this kit an excellent upgrade. I received my parts much faster than I expected. I highly recommend
great service. Spoke with customer service and they were very helpful. Would buy again from MCARBO
Works good
same
I ordered 7 different spring kits from Mcarbo. I followed the video to the letter (one star given is for the only positive thing about this -the video was good). My factory trigger was 5# on RCBS triggerscale. After installing the Mcarbo kit, it is now 5.25#. Unusable IMO. The video depicting one and a half pounds must be a trigger that was purposely selected for the video because this is completely unrepresentational of the typical 77/44 trigger
This rimfire arrived with a 5.5 lb trigger pull. After adding the shim, spring, super lube and lite polish of trigger and sear I have a 3.5-4 lb trigger. I am delighted as this is about the same weight pull as my Ruger centerfire rifles. Very fast shipping plus (being a veteran of Vietnam) I am delighted to see a veteran run company doing well.
Outstanding product and service. I goofed my “Stars” on previous review
The spring installed easily--I didn't use the bolt shims. Trigger is much nicer now. I had previously (long ago) put another brand of trigger upgrade in my 77/22M so I was somewhat familiar with the operation but the video was a great aid and if you do this easy upgrade watch the video first.
Way overpriced and they should offer the sear spring only anyway!
I put .003 (.001+.002) and the bolt closed but it was VERY tight so I removed .001. closes acceptably now. I did not not need the trigger spring as I had redone the trigger previously, it pulls at around 7 ounces. I was a match shooter in high school 48 odd years ago. We shot Rem. 40X and Win.52D. The rule was do not touch the trigger until you had the sight picture. Well learned lesson that is needful for whisper light triggers. Any way my M77-.17hornet is x ring accurate now.
Trigger Adjustment Spring Kit-I ordered two of these for Savage upgrades. The video and instructions were perfect -Reduced the trigger pull by almost 4lbs. The item is Captain Raimey Approved
excellent product
This kit reduced my trigger pull from almost eight pounds to about four and a half pounds. I would like it to be a little less but mcarbo has me in much better shape than I was in. I would highly recommend this product to anyone with a m77 that has a heavy trigger pull. A few of my family and friends have m77/44’s and I will be encouraging them to get this kit.
This kit addresses two of the several issues that the 77/22 and like models have . These triggers from the factory are safe in design as no way to adjust pull weight or sear engagement period so being stuck with uneven surfaces tool marks ect on the trigger and sear as well as a full sear engagement some of these models might not see a huge improvement and some will mine was reduced by 12 oz and was very consistent in the measurements and by polishing the mating surfaces between sear and trigger and removing the rough finish I might have increased the surfaces touching each other causing the lack of reduction in pull weight that some have experienced. With that said the kit does reduce pull weight. In my experience with the wood stocked models the main issue with accuracy with these Rugers has been rifle bedding or lack of , if You doubt this assessment free float the barrel then You will quickly see this as all of the bedding is the barrel touching the barrel channel and no where else as the inletting for the action area is way to generous for the best accuracy
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.
