AEG Spring upgrade

[sawmonkey]

I have a classic army G36c which is stock and producing an average 280-290 fps. I wish to upgrade the spring to produce an average 335 fps for use at my regular site. Will upgrading the spring to this cause much if any damage or excessive wear to other parts?

If that's all you're aiming for it shouldn't be a problem. Don't be surprised if you don't notice a difference in performance though.
