Easy fix I was looking for

Rating:
Pros:
Cons:
How do I justify gunsmithing fees to fix a trigger on a rifle I paid less than $200 for? I simply wouldn’t, and I would accept this trigger as heavy, cruddy, and the rifle would hold a neglected place in the back of my safe for eternity. Enter this handy MCARBO spring. Easy to install (thanks to their YouTube vid), and the rifle is born anew. I don’t use a trigger pull weight gauge, but subjectively it feels like half the weight it used to be. The “breaking wall” characteristics didn’t change much, but the lighter weight acts like a more finely tuned instrument to allow the subtle nuances of the break to shine through. It used to be a brute force operation to get it to break, and now I’m able to feel more precisely when the hammer will fall. So far, safety still works and everything functions as normal. If you have one of these rifles, this is the cheapest and most effective mod on a trigger I’ve ever experienced, and I endorse the results.

Works Great and easy to install

Rating:

Let me start with Thank you for your service! My family and I greatly appreciate your sacrifice. The spring kit for the Marlin 917V works perfectly. Installing the spring was simple after watching the video on your website. I measured the trigger pull before and after. Before I installed the new spring the trigger pull was 3.75-4lbs. After the installation of the M*CARBO spring kit the trigger pull is 2.5-2.75lbs. Trigger pull was tested using a Wheeler trigger pull gauge. I couldn’t find any gun grease with PTFE locally. I used Outers choke tube and gun grease. I believe my trigger pull will be even lower when I clean out the Outers grease and lube with a grease with PTFE. Again thank you for your service and thank you for providing a high quality replacement spring for the Marlin 917V!

Significant Improvement Over The Factory Spring

Rating:
Pros:
Cons:
The new trigger spring was a worthwhile upgrade to my old, but accurate, Marlin 883 22 mag. No issues with the fit or install - very simple. Trigger pull was reduced about 50% to 2.5 pounds. Never really minded the heavy trigger pull until I used this rifle exclusively on a ground squirrel shoot last April - after 400 shots in 3 days I knew I needed to upgrade. Had planned to change the entire trigger, but thought it was worth taking a chance on a $13 spring...what's the worse that could happen? Glad I did. And so will you.

Worth the money

Super easy install, trigger now breaks at two pounds.
