Hello, this is my first time cutting a spring and im just looking for some feedback. Unfortunately i dont own a chrono yet. I read the guide on choosing the right spring and making it work, it said one coil on an m130 would be about 20 fps. But my spring is an m120 and I'm trying to lower the fps by atleast 30ish. Does it look like I took enough off?

You should see a significant drop with that. I would just try and clean up/bend/flatten the cut end. 10/10 buy a chrono.

edit: if you don’t own a chrono then why did you decide to cut the spring?
Thanks. Well I chrono at the field and I was over 400 fps, and the rifle is advertised to shoot 420. Trying to get it below 400 so I have less of an MED and can play more aggressive without having to switch to a sidearm
