Spring for GR25

[Chopper92]

Hi Guys

Looking for a new spring for my G&G GR25 as its only shooting around 250-290, any suggestions on something that will boost it up to proper DMR FPS?

Also has anyone done this with a GR25 before?

How hard can it be right?

Cheers

Depends what FPS you mean as it could be anywhere from 380-500 FPS depending on where you play. I'm pretty sure a load more internal work needs doing to get an AEG reliably shooting once you put in a stronger spring but i'm sure people on here who know more than me can fill you in on the specifics.
