G&P V2 gearbox thoughts.

[knarf3]

Picked up a couple new g&p gearbox's for a couple of builds and just wanted to get people's thoughts on them.

I will be correcting the AoE with a sorbo pad and think its best to swap out the spring as I have no idea what fps they will be pushing.

Anybody got any recommendations on what spring to use to get about 330fps out of them.

Also any advice on bits that are worth swapping out while the box is open.

Many thanks

Just realised I put this in the wrong category. Mods please move to AEG tech.
