m24.cyma.cm.702

Greetings! I have used the search but couldn't find anything about this replica from CYMA. I have a CYMA M24 (cm.702) and i'm looking for some parts for it. I've got no manuals for the gun in the box it came so i have no clue - it is APS, right? Or is it APS-2, or is there no difference...
