Our take: This M249 series magazine holds up to 1,200 rounds, giving you four times the amount of ammo-carrying capacity of most high capacity mags. This box magazine is powered by a 9V battery (not included) and automatically winds and feeds BBs into your AEG. While this box magazine is designed for the Classic Army M249 AEG, it also fits perfectly into the Classic Army MK46 SPW AEG Machine Gun.
NOTE: This M249 series electric-winding box magazine will fit into A&K M249 AEGs with slight modification.
