Snow wolf M24 upgrade spring

[CaptainH]

Hello. I was just wondering if there is any specific spring needed for a snow wolf M24 for it to shoot around 320-325.

Thanks

I've never heard of needing a specific spring for one gun...

You will probably want and M110 or M120 assuming you're using .25s-.30s but it would give you around 390-400 using .20s.
