getting a gun working vs properly tuning a gun are 2 very very different beasts.

You can throw a set of gears into a gearbox and not even shim them with a plastic piston body and it will work. How long it will work for is the question.

I believe my g36 is at about 30k rounds put through in 2 years without a single gearbox issue. I built an ak for someone and he puts about 10k rounds through it a week and it has no issues aside from the body pin he lost, lol.

There's guys that still believe dry firing is bad for your gearbox, while I've sat there with my trigger held down full auto at 32rps with nothing in the gun to see how much the motor will heat up in extreme circumstances.

I've seen guns put back together by guys who say they're good at working on guns break the very next game... but hey, it worked for half a day. There's a whole thread in the gundocs section about guys who tried to do it themselves and failed quite comically.

Just take some time, read the forums at airsoftmechanics or some of the other big forums, even here, but asm has the least amount of tolerance for bullshit, snake oil practices.

Just don't throw money and parts at a problem without understanding the problem first... that's the key to being a good tech. You can learn on any gun as long as you can be patient with it. Lots of guys get frustrated at taking it apart and putting it back together so often than they start to rush their process, which will lead to things going wrong.
