Easy install fast shipping
Installation
The review is for fitment and installation.
Removal of existing and replacement with the MCarbo spring is a fast and simple process.
Replacement spring slides in place very easily.
Trigger feels cleaner, but I have yet to fire it so cannot attest to the specific trigger pull weight reduction.
For the spring kit price there is very little risk so a slight improvement is worth the cost
Winchester model 70 trigger spring
This spring was easy to install and delivered a crisp 2 pound setting.
Winchester Model 70 - Trigger Spring replacement
Amazing results and easy installation. Works as advertised, factory trigger pull was over 5 pounds. M-Carbo spring installation resulted in less than 2 pound pull, crisp break with no creep.

Amazing Game Changer
This spring took my 5.5 pound to 2.5 pounds on my early 90s Model 70 Stainless Classic. The instructional video was clear and the result was perfect right down to the over travel. The trigger is smooth and crisp with a clean break at the wal. Don't try and mess with the factory "adjustment" get this spring!
Model 70 trigger spring
Ordering was simple , shipment was fast . easy to install .
It was a good day. Thanks gentlemen shoot perfect.
Winchester Mod 70 super grade, 1970 vintage
OEM on lightest setting was 4.5lbs. Installed this spring, now at a desired 2.5lbs. However, you lose the adjustability with this , luckily it came out right where I wanted it. A little pricey for a single spring, but was worth it since they did their homework and got it right. Still way less expensive than an aftermarket trigger.
Will the spring work on Model 70 XTR Featherweight rifle?
Will this spring kit fit the, short action, "Pre-64" Model 70?
Yes, any Model 70 before 2008 with the original style trigger.

Will this work in a Winchester 670? Budget version of the model 70.
How do I know if my gun is before 2008
Take a look at the infographic on the Description. The serial numbers are associated at the end of the year of production. If your serial number is in the range of the years Before 2008 or after 2008 you can see it from there.
This spring kit will work on a fetherweight ?
Functions in all Winchester Model 70 calibers and variations over the years.
Will this trigger kit work on the xpr rifles too? I assume they would seeing as how they also use the moa trigger system
I just installed it on an XPR. It is tricky to install because the trigger housing is not removable but it works. Trigger down to right over 3# from right under 5#.

We haven't tested the spring on that firearm, we cant say if it will work.
