Assisting a friend with some research on his MAK 90 and a few accessories....

2-30 round magazines with markings stamped into the raised, spot welded spine as follows:

Mag 1- X E O I F S C B Q

Mag 2- J H F H C A

Both mags have a witness hole at the 30? round mark, not "bolt hold open" types, no other discernable markings.

Any idea what country? age? etc.?

Thanks!

Steve
