Nothing is worse than firing your last magazine empty in the middle of a firefight, only to realize that you're now out of the fight. Meanwhile, your friend's got more BBs than Mach 1 Airsoft... but he's using a completely different gun. If only you had a way of sharing magazines. Now, with the ICS Drum Magazine, this can be a reality. This Drum Magazine comes with a M4/M16 connector, though you can purchase an adapter for most other guns. Modelled after the Beta C-Mag, this magazine will carry enough ammunition for any use you could possibly think of.
