I’ve seen other animations in the past that didn’t get into as much detail as this one. In this video you get a pretty good demo of how the various parts work during the firing and automated loading of the AK-47 but they got the trigger wrong, etc. This one shows the disconnector and trigger hook operating in the right manner for example. I’m posting it because I think it always helps to understand what is going on inside a firearm for when you want to tune it, figure out what might be going wrong, and so forth.
I’ve always found the IMI Galil rifles one of the more interesting variations of the Kalashnikov AK design. I thought you might find the following links of interest if you want to learn more:

The following video is very informative. It shows the rifle being made at IMI, interviews designers and talks about some of the unique features:
In case you missed the original Tales of the Gun episode on the AK-47 when it aired in 2010, here it is. This is a very well done episode that goes into the history of the design and how it served in battle. Fans of the Kalashnikov will definitely want to watch this.
By the way, what I like about this particular Youtube video is that the quality is pretty good and it is the whole episode vs. being chopped up.
This is a very interesting video that covers some of the history of the AK-47. I found the portions showing testing and manufacturing very interesting.
