Here is how to become a menace in CQB games with the new G&G ARP9 PDW AEG, get the 1,500 round drum magazine made for it. That should outlast an enemy lurking around the corner as you can move in quick if you notice he/she is reloading. Available right now at a reduced price of US$55.00 at Bunny Workshop, this is made of Polymer and you have to wind it manually.
