Lonex M4/M16 Hi-Cap Pull Cord Magazine Disc
Spare high capacity (360 BB) magazine for the M4/M16/Armalite style rifles. Should fit any Tokyo Marui M4 compatible AEG (other than M4s these can fit some SA80s, Scars, FN2000, some M249s etc).
This uses the new pull cord wind up mechanism, fill the reservoir, flip open the bottom of the mag, pull the internal cord around 10 times and fire till you empty the magazine! The cord itself is made from metal braided wire and as the outer is made of metal which are both are incredibly tough!
