Does anyone on here know anything about the GSG 522? I've had one for some time, and I really like it. But in a recent game my charging handle broke off. Without it I cannot disable the blowback or set the hop. I have taken the gun apart and found where the piece broke. The only problem is I cannot find a spare charging handle anywhere online that would fit my gun. All of the airsoft ones i can find are too small and all of the real ones are too big. I've considered my best option might be to buy a jeweler's saw and cut up the broken piece and use it like shims on an airsoft charging handle. Does anyone have a better idea or any advice? Or if someone knows where I could buy this piece, that would be very helpful.
