4 minute install and makes a good stock trigger even better. I love my 930 tactical--so much fun to shoot and it already has a bunch of OR3Gun accessories.



MCARBO should poll their customers to get an idea of commonly owned firearms for future product ideas.

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.

I needed the spring kit for the sa-20/sa-28. I am returning the wrong kit. I finally got the installation video, which was not available when my order was received. Also,there was no grease in my order. I feel that the grease should have been included.

Awesome company!!! Part was delivered earlier than posted. 5 stars

This product is absolutely a must if u have a Mossberg 935 it definitely makes the trigger alot easier to pull and is very easy to install service was very quick and the shipping was on time like they said it would be
