G&G M4 – 2300 Round AEG Hicap DRUM Magazine. This is the largest drum magazine you can get for the M4 AEG. Fits in all M4 and M16 AEGs made by nearly all companies. Screw midcaps – get this beast mode mag and dominate the entire battlefield with a smug face.
The battery is included (charger not included). Use a 7.4v small lipo that fits inside, then you can charge through the JST balanced connection on the outside. Any 7.4v lipo will work, like a 250mah or 1000 stick should be fine. The drum has a switch if you want to change from electric-wind to manual wind.
Full polymer build, easy to wind, load, and use. Very smooth function for the pickiest airsoft player.
