It is called a magazine. To a firearms purist, a clip holds cartridges until they can be inserted into a magazine.
=========================
If you wished to be more technical, it would be a "20 round detachable box magazine" (30 round magazines and any other magazine which fit the later M16A2 and M4 would also fit in an M16A1). The original models made by Colt were aluminum, and the follower was also made of metal (most current production magazines for the AR15 and other STANAG 4179 compatible rifles use plastic followers).

It depends on what state you are talking about.
There have been several variants. Most commonly, 20 round or 30 round magazines, but may use a 40 or 75 round drum.
Well, it is actually called a magazine, not a clip. The standard M-16 magazine holds 20 cartridges, extended magazines hold 30.
