Spring Upgrade for MP7 v3 Gel Blaster * Easy FPS Increase*

Swapping this spring out with the stock spring is the easiest way to get an effortless increase in FPS. I've been persistent in using the M85 spring on an 11.1v battery and the plastic gears are handling it fine. Of course please upgrade your blaster at your own risk.

How is the blaster doing? I'm interested in upgrading my spring but have read that it's not recommended due to gearbox design.. I'm concerned with longevity

[@LONGCAUSE]

Do you use the v4 or the v3?

[@mickaelvella]

@@LONGCAUSE v4

[@Bossgaming60105]

You could upgrade the gearbox to full metal probably
