Spring Kit 930 Mossberg

Pros:
Cons:
Just follow the video and do not release the trigger. Life will not end but there will be a learning curve. I own 2 binary triggers and this is no binary trigger. The good news is, it don't cost $400.00 Bucks. I was truly amazed at trigger response after installation. Definite improvement. If this spring holds up, this will be one of the top purchases of my gun loving history. Thanks! M*CARBO Bro's!

Well that was easy. Great improvement over factory, not that it was all that bad to begin with, absolutely felt the difference before and after applying the grease. Shipped same day as ordered.

Excellent Upgrade to the Mossberg 930 Trigger Group

Rating:
Pros:
Cons:
I found this upgrade to my Mossberg 930 SPX's trigger group to be excellent! Trigger pull is noticeably smoother and lighter without being too light for my purposes. The weight of this spring is well chosen and appears to be manufactured of quality materials. Yes, it's a spring and a fairly simple part not to mess up but, I have seen poor quality springs just the same and this is not one of those for 100% certain. I also bought and used the PTFE Synthetic Grease for the sear engagement contact points and that worked well in combination with spring in smoothing the trigger pull. Glad I bought and extra tube to use on my other triggers. Great products M*CARBO Team. Thank you!

I have a mossberg 930 jm pro. I measured between a 5 and 5.5lb trigger pull before. And a 4lb trigger pull after. So I am very happy. Any lighter and I might be worried during competition.
