It's a split gearbox - easy peasy spring change

look up "spring change ICS split gearbox" on google

or you could cut the spring which is what I done to mine. Got it down to 320fps

I think it would be easier to change the spring but if you have the knowledge then you could cut it down then it's free.

How many rounds have you put through it?

I had an ICS M4 running at 360fps out of the box, put about 600 rounds through it and it dropped to 345fps and stayed consistantly(ish) there.

I know that may sound like crap but i figured it just needed a few rounds to bed the hop in etc?
