I have recently been promised one of these by a friend, and since it is my first airsoft gun ever, more specifically being a GBB pistol, I was wondering what I should start out doing with it as soon as I get it. I am unsure of the overall condition and want to make sure that it is in proper working order, including the 3-4 magazines I am getting, but don't know where to start at all. I'm assuming I would have to disassemble it first and formost, and clean it out, and then lube, but beyond that is there anything I need to keep in mind, since I haven't worked with GBBs or even AEGs at this point. And is there any recommendations on what type of grease I should use with this as well?
None of the mags leak, I actually have it taken apart right now because it has some clay stuck to some of the metal parts, so I'm just cleaning that up with some rubbing alcohol. When I have it cleaned up I'll post a pic. Need to get some silicon oil though before I use it, since it looks like the previous owner used some kind of graphite based lubricant.
Edit: Asked a friend in the air force before cleaning to make sure. Only using the alcohol on the plastic parts. Gonna use WD40 as he suggested.
