Hey, a thing!
I wanted some animations for all the AKs on Gamebanana, so I made some. They're based on Dan's AK, (an updated version of which can be found here) so they may be a bit "loose" or "tight" on other skins, I haven't tested all of them.
This download does not include the AK skin used in the video, just the animations. You must find/use/provide your own skin (or not, if you just want wacky smg animations). Does not include inspect anims because I really don't care about that feature.
