FWIW, the Pakistani copies are just uniform modern plastic, sometimes painted, never real AG4 'bakelite'.
These are all fakes, photo credit to someone else obviously
I was watching a video that showed some Pakistani made bakelite mags
Some as you said were obvious but others have done quite a nice job of trying to fake the woven pattern of the AG4 and markings
Check it in this video (skip to 3:09)
I had to stop watching as soon as he said "clipazine"
