Worthwhile upgrade

MCARBO makes buying and upgrading parts so easy. The unconditional lifetime warranty is something that made me more confident of my purchase.



For my Mossberg 930 SPX the trigger pull was 5-5.5 lb. To install, you simply use a punch to take the fire control unit out of the shotgun, take out the old spring, insert the new spring, align the holes and place the pins back in.



I get a nice crisp 3.8 pounds from my Timney manual trigger scale. The action is so much more comfortable.



It is definitely an easy and worthwhile upgrade. I highly recommend it.

I ordered and installed the trigger spring for my 930 S P X any problems that I encountered were minor and were the result of my not paying better attention to the video directions. I went back and reviewed the directions more carefully as well as consulted with a schematic.Just another in a long line of AW SHIT MOMENTS.

I am happy with the results and glad I installed it.
