Here is the installation video where we go over what's included in the kit as well as how to install it. It's super easy and straight forward.
Here is the spreadsheet mentioned in the video where you can see how each pin affects the power on a typical M150 spring with a standard length inner barrel.
If you end up doing similar testing with different spring / barrel setup, let us know and we will gladly include the data in the spreadsheet! Just make sure you do it exactly the same - 5 shots, measured in both Joules and m/s.
