When you purchase this mag, even though the box where the mag is stored in says "REQUIRES M16 HIGH CAP MAG" to work, it doesn't. it's already included and built in.
Another thing to note here is the back of the instruction. It tells you to stick some type of "rubber" in to the middle of mag but you don't have to. And I have no idea what it's talking about. It's working flawlessly without that "rubber" that didn't come with the purchase. Don't get confused by it. It's ready to use out of the box.
PS: No one cares =(
