The Mcarbo trigger spring kit reduced the trigger pull two pounds. The original pull weight was 5-1/4 lbs. The trigger pull was 3-1/4 lbs after installing the Marlin 917/925 Mcarbo trigger spring in a Marlin 882L 17HMR. It took only a couple minutes to change the springs out.

I have an older Marlin Model 25. I like others contemplated the ball point pen spring to help with the hard trigger pull. It didn’t feel right to put in a “throw away” spring. The M-Carbo spring not only reduced the trigger pull on my rifle but also gives me the confidence of a quality part. Highly recommended.

Marlin 925 trigger spring

Rating:
Pros:
Cons:
Starting trigger pull average 3lb 10oz

With M*Carbo spring average 2lb 9oz



So the question. Is the M*Carbo 917/925 spring worth the money for one pound?



A. Yes, supporting an awesome company like M*Carbo, definitely.

B. Yes, I put a $300 trigger in my AR15 so what's a sub $20 spring (with shipping) in my marlin.

Awesome Spring

I've had my Marlin 917v for quite a few years and as sometimes happens it ended up in the back of the safe and forgotten about. Last week I pulled it out, took it to the range and remembered how much fun it was to shoot. Like most things I own I just can't help but tinker with stuff so I started researching the trigger on the 917v. I found some forums and was seriously contemplating the pen spring trick. Thankfully I came across the Mcarbo site and watched the video. They bring up an excellent point; why skimp out on something as integral to the safe operation of your firearm as the trigger assembly by installing a cheaply made spring designed to be thrown away. Seriously, who can't afford $12 and some change for a quality spring designed specifically for your application? I'm glad I did. I installed it yesterday, tried it today and immediately noticed a difference in my grouping. Anyone wanting to improve on the 917v shouldn't think twice about this spring. Well worth the money!
