Clip, a stripper clip like for bolt-action rifles, or the en-bloc clip like you load the M1 Garand with from the top.
The Brady Bill/AWB banned MAGAZINES. An enclosed, spring loaded feeding device for ammunition. Some are removable, like semi-auto handguns, M16's, AK's etc.
Some are fixed, like the M1 Garand, SKS, and most bolt-action rifles.
You can use a CLIP, to quickly stuff rounds into a MAGAZINE.
It was Federal law that in '94 they had to stop making magazines over 10 rounds for any semi-automatic firearm, unless they were marked "LEO and MILITARY ONLY". All magazines made prior to '94 were still legal to buy, sell, and own.
In 2004, the bill expired as there was enough pro-gun votes in the House of Representatives to prevent the bill from being renewed. (Pro-gunners, and "moderates" put the 10 year sunset into the bill to give a chance to see if it did any good.... None obviously)
During the '94-2004 "ban", the prices went way up in some cases, but there were plenty of magazines over 10 rounds for the firearms that took them, for anyone who wanted them badly enough.
Some states (and some cities) like California have thier own 10 round limit, and those haven't expired. However, most states aren't any stricter than Federal law.
