They are called magazines, anon… magazines.
Ugh, no, you have been given wrong information by the media entertainment complex.
An ammunition clip is a device used to store individual rounds of ammunition together as a single unit that is then ready for insertion into the magazine of a gun.
A clip is a very simple device that is usually made of a steel stamping. There are various kinds of clips, the most common of which are called en bloc clips and stripper clips.
Again, these devices are used for loading ammunition into the magazine, which then feeds the individual rounds into the firing chamber.
For rifles with an internal magazine, the clip loads the bullets into the firearm itself.
Some rifles with detachable magazines can be loaded with clips, but this is relatively uncommon.
For all of the confusion surrounding clips vs. magazines, clips themselves are relatively uncommon, as most modern firearms do not use them at all.
