So I was taking apart my CYMA CM.050 AK the other day. Not to do anything with it really, just for the fun of it. (I don't know how to do anything with airsoft internals. Modifications, repairs, etc.) While I was pulling out the gearbox, this happened: I've done it tons of times so don't tell me I shouldn't have done it since I'm an inexperienced airsofter. I just want to know what air nozzle to get, and where to buy it. If there's anything else I would need to repair it, please tell me what it is too. Any help with this would be great. Thanks.
