    I've been looking at and becoming attracted to the g&p m870 series. I am really considering buying one but the big drawback is the high fps. If I were to downgrade it would it even be possible and how would I know what spring to use to bring it all the way down from 430 fps to 300 fps

    Yes, it's possible, but it requires disassembly of the gun and gearbox. And an M90 spring should put you near 300fps.

    Either buy a lower powered spring, or just cut some coils off the existing one. But only do it a few at a time, then re-chronograph. But remember, once you cut it off, you can't put it back.

    Yeah, I'll think I'll just go with buying a new spring, so if my friends are being jerks and I want to hurt them a little more ill just take the 300 fps spring and replace it with the 430 fps spring

    You could, but if you go to an actual field and do that, you will most likely get kicked out/ banned.
