Parts help
 

Gday, I just purchased a Classic Army Styer AUG A2. I was putting the mag in and found it was loose and wouldnt fire out BB's.
On closer inspection i found the tab that mates the mag to the hop up was broke,(plastic).
I have tried to bond it with a few different things but my experiences with plastics is that once it's broke; replace it.
So, being very green in the airsoft world, I'm looking to find the part off my parts schematic in my manual. PN AUG050-1. Any help locating this part locally would be much appreciated. No luck so far thru Classic Army site.
Thanx in advance to all feed back.
