Got my first AK....basic questions

Hi Guys. Your typical AR15 guy here. Eat, drink, sleep with my AR.

First post here. Hope y'all doing well.

Got myself a Riley RAK-47-C-SF cause I like buying guns and storing them, never to see or use them for the next 100 years. What can I say; that's my weird hobby.

1) Can some one please, point me to a simple beginners user manual for my AK please? The Riley box says that I can find a manual online, but I can't. I don't want to guess how the AK works. I rather pretend this is my first rifle than just guess how stuff works or how stuff is disassembled etc.

2) The rifle has a foldable triangular stock. I want to change it to an Underfolder stock. I looked on google and I am not sure why I cant find a lot about how to switch from a triangular to underfold stock. Must be google's search AI in control freak mode today.

Thanks all for the replies!
Be Well!
