I reciently had a event and ran threw ALL my ammo. I used about 1,000-1,500 rounds on my Semi auto only gun shooting 435-440fps w/.2's. I just got done taking my gun appart a week later and there is absolutely NO wear on any of the piston teeth.
The piston is a stock JG piston which I believe is a stock TM piston. It's amazing, I though I'd strip it while on stock gears and a M130 spring...
Now, next part. I want more Fps... I'm thinking of buying Hurricane Ultra Torque up gears (

My gearbox had no problems last week. There are pretty much no signs of stress marks on where a usual Version 2 gearbox breaks.
Let me know how good Hurricane gears are. I though about Guarder gears (

Also I want to get a silent Piston head. I already have the cylinder head I just need the piston head...is there some place where I can get just the piston head?
