MAG - AK74 Mags Work best
ehobby Asia has them
I use them too. A bit pricey for a box but worth it.
It can feed for fast rate firing.
Lipo and 12v NiMh battery works well with these mags. No Jams and if you use such a high battery power like me you can pretty much simulate the bullet effects on sand like a helicopter machine gun would in desert chase scene
