5.56×45mm id help

Any informations will be helpful.Thanks very much!

Magnum, can you tell where it was found?

It has a “Singaporean” look to it.

It was made in China by Chongquing Changjiang (Factory No. 791), but I don’t know who is the customer. My first thought is the Republic of the Philippines, because I know they purchased 5.56 mm ammunition from China, but I have never seen an example of the headstamp used for this contract.

Fede, is there a source for this info?
