How many grains of sand exist in my math teachers vagina? No one knows the exact answer.
BUT on a GBB, the things that will go first is the plastic slide if you run propane for any extended period of time. Depending on the gun, you may have things like hop up rubbers get swollen and warped or may break your mag feed lips if your too hard on them. There are lots of things that can break, its just a matter of when. With that said, there are people on here that are running some really old GBBs without too many broken parts.
This is why a gun with good aftermarket support is something to consider when choosing a gun.
