2ThunderCactus, not quite.
Since mid October (

I'm "tearing apart" my TMG36c. At first i did it to test the idea of using Systema turbo motor in high power setup (420FPS) and then to test various FET setups (btw, i believe that we've finally struck gold, will post later). Since then, together with my esteemed colleague mr Bulldog, I've fired at least 20K bbs. Recently I've opened my gearbox to check the wear'n'tear and... nothing. TM stock internals look as good as new (the gun is almost 8 month old). On the other hand, my friend's complete systema mechbox already had 2 piston replaced in the last 6 month. Cannot say much about the gears, had mine replaced with Systema ones.
