***If you have a Mossberg 590, then you will need to remove both hammer springs that are in the Mossberg 590 Trigger Group from the Factory. There is an inner and outer hammer spring that fit inside one another. Then replace the 2 factory springs with the single M*CARBO Hammer Spring in this kit. We've thoroughly tested this to ensure it would be free from light strikes or discharges when dropped. Due to the Mossberg 590 being used by the Military, it includes 2 hammer springs from the factory to ensure it will ignite harder primers on military grade ammo. Unless you are shooting military grade ammo you will not experience any light strikes.***

The spring kit worked very well, highly recommended it. The video made the installation a snap. While installing the kit I found that the safety part was poorly machined and I was able to clean it up with a file. The safety on my gun always worked hard and after the installation and cleanup the safety works well. The spring kit is a great upgrade to the trigger feel.

This is an amazing upgrade that you can do yourself in less than 30 min, the part got to me very quickly however one if the springs was damaged in transit, at no fault to the seller. When I contacted them about purchasing another spring without hesitation after hearing why I needed it they sent me another spring at no cost, this is the best customer service I have experienced, so not only am I happy that my trigger now has a pull a little over 3lbs but I'm happy that there definitely out to help there customers.. Thank you for everything!

The video makes it look easy, but a little harder for me to do. Trigger pull reduction of a few pounds is not what I expected but good enough for a shotgun considering the crunchy pulls that most shotguns have. I still like though, Thanks MCARBO.
