In theory every 5.56 NATO mag out there should meet the NATO standard (I can't remember the STANAG number off the top of my head). Which is not a bad idea when you think about it, so you can resupply from any NATO forces around at the time.
The fact that the A1 magazine doesn't seem to merely reinforces its status as crappest assault rifle of all time.
There is a new Blank Firing System coming in. I have read the signal on this and seen pictures. It comprises of a modified BFA, which will withstand up to 3 live rounds fired through it, and a new magazine, which can only be fitted with blank rounds. The bottom half of the magazine is painted yellow.
As an SAAI, I think that something like this is long overdue. Poor range checks has caused too many injuries and deaths, so this new system will hopefully prove invaluable.
If I remember to bring the signal home, I will give you its proper name.
