Metal body compatibility

[FryFubar]

Hi everyone,

I might be obtaining an M4/M16 varient from the forum's classified section, but I want to upgrade the body to one of the aftermarket marked bodies (Hurricane, Guarder ect)

Has anyone found some sort of list of compatible bodies? I've tried googling and searching these forums for hours now, but I've turned up nothing really helpful.

I might be getting a Dboys based AEG, just wondering what brands will fit and are they interchangable with other m4 bodies.

I'm already aware that Dboys clone the main airsoft brands (TM, CA ect) but I'm not sure to what extent.

Can anyone help?
