ACM / Battleaxe Steel 400 Round Hi-Cap Magazine for Tokyo Marui Next Gen Series M4 Airsoft AEG (Color: Black)

"My buddy has a few of these mags for his TM 416 and they work perfectly. I've used the 416 in a few skirmishes and they have never seamed to fail even slightly, they where also brand new so I don't know how they are feeding now but he is still using the gun and hasn't complained about mag feeding. Also the other guy giving the mags a bad review because his speed loader doesn't work on a hicap magazine is totally unfair.
