Every AEG I own gets a nice new shiny systema red polycarb piston. Gears I dont mind keeping whatever is stock, the only thing I would consider using for a swap out would be modify gears. But I usually just leave it as is, as my upgrades dont require much more than a good spring guide, and spring guide. The pistons just cause for fun.
