Cobalt meant no offense by his suggestion. We here at ASC support good grammar, which is difficult in this day and age of text talk, and laziness. We often have people whom do not take the time or care in what they say, and English is their first language. Your English is quite clear, and I recognized that it was a mild language barrier, and not an issue of grammar. Have no fear, we are simply being vigilant, and it is not our ideal to be proud or abrasive.
On to your question. It is indeed possible to quiet an AEG, and to upgrade your Cybergun. As noted above, Cybergun is a rebrand and therefore you can get good ones; however, they are generally regarded as being cheap junk. Also a cheap gun can cause you to have more problems in the future. A close friend of mine had a similar project a few years back. When he was finished there was nothing left of the original gun, and cost him exponentially more long term than if he had started with a better platform. It is completely possible to upgrade your current platform however. The unfortunate part of your situation is thàt as you change your gun internally, it will inevitably change the sound it makes; perhaps even to sound you don't like. So either option is possible, but my personal suggestion is to start with something that will give a better project, and eventually a better gun; then work on quieting it. There are a few tricks out there to dampening or changing the sound your gun makes.
On another note, ASC and its members cannot tell you where to get guns or parts until you have been age verified. We do this to keep guns out of the hands of youth, and to protect the integrity of our sport in Canada. Please get age verified so we can assist you better.
