A&K 5000rd Electric Winding Drum Magazine for M4/M16 AEG
This mag is great. The only bad things about it is that I had the version that you had to wind and one part that you put the bbs in got shot out by a 350fps gun and the bbs fall out. Also it came with a foreign charger and im from the U.S. But other than that it is great. Like it fits and my m4 like it was the mag that came with it. So if your looking for a good mag for the m4 look no further.
