i would like it to be like that to give my gun a bit more "OMPH" .
i had just put a Madbull 509mm barrel in it and a systema hop up,
and it does not really move far ( i kinda want it to be a sniper m4 )

i asked the guy that own's or runs ( i think ) Elite Action Games Worthing and he said
"along as i have something physicaly stopping the gun from going to full auto im allowed to have up to 400fps on semi auto, but no higher"
So does anyone know what i need to upgrade to be safe??

JG M4, eh? What model? Give me the specific manufacturer code (i.e. BI-3881 for Boyi guns) and I'll tell you what to do

Well... just get the spring
this is the website i got it from http://www.actionhob...Tone_AIV4G.aspx
I suppose your gun has 330 FPS because it's adjusted to the laws/rules in UK. Thankfully, I don't have such problems and had tested the same model shooting at 430 FPS (stock in Poland), also tried it on a M150 spring at time. And it lasted.
Anyways, the model's the same, so it seems they just changed the spring - I doubt they'd put in another gearbox. And remember: JG guns are tough. Real tough. ###### tough. John Rambo-type tough
