apparently many hong kongers use Chinese guns as platforms for upgrades.

I've noticed that many of the threads on upgrades tend to be based on old information, he said she said that he said that upgrading this and that part was essential etc. This information gets passed on enough times that it becomes gospel.

Not everything is true however. For example, JG gears are different from TM gears - they have epicycloidal design - similar to that from systema gears. Some say they are actually CA gears.

So what does this mean exactly? It might mean that JG gears are good enough as it is.

Therefore to bypass all the hearsay, let's talk about real-life experiences. Tell me about your real-life experiences about JG guns. I've read the thread about long-term reliability, and not one of them talks about gear failure in a JG gun, and there surely must be more than 3 people in Canada who owns a JG gun!

So the question: what kind of failures have you experienced in a JG gun, what was the gun, and what was the fix?

The purpose of the answers is to determine how best to create the ultimate upgrade to a JG gun (the one I'm specifically interested in, is the M4 series)

Thanks!
