our local field doesn't allow hicaps most games. those that do use them, are extra loud. either way they are obvious or waste more ammo then necessary. i would imagine any polymer style magazine would be possible for the AKG line.
therefore, it would not be outside the realm of possibility to do the quadstack experimental magazine. it would mean a massive reservoir in fuel and 80+ bb's in that mag. i would love to see that.
ya know what would also be cool. as far as the magazine design. think of all the GIM (gas in mag) guns. drop a magazine and that precious feed lip loves to find the nearest rock and crash into it like a meteor.
how about the AKG mag has feed lips. this acts as guards for the entire release area but it would mean a entire redesign for the functionality of the gun.
another thing i would hope would be practical for buyers and kwa was the ability to change the magazine shell color. like skins maybe, combloc airsofters have an erotic love with different 5.45 style mag colors other then black. like when you slide open a m4 hicap mag. just like that to change the color on the AKG mag. sell them in packs of 3's so production numbers can be met more easily. it all depends if AKG mags will come in different colors or not. plum would sell the best, I believe. especially if the color palette were done spot on.
