After shooting about 10 000 rounds on my m16a3 i opened the gearbox to see the internals,there where no damge i could see beside minor gear wear on the piston,but negligible.Tons of grease,get some rags before opening.I would sugess to redo the shims,mine had too much slack.Put in a softer spring like a modify s90 and some new grease and you have a rock solid gearbox.A madbull 6.03 tightbore and a guarder clear hopup rubber did wonders for my g&g.Cheers.
