Manual of Arms of 20th and 21st century

As the title says, I'm looking for a Manual of alArms that covers the most common firearms of the mid-late 20th and 21st century. Tried looking around online but didn't really find anything that fits my wants. I'm looking for something that covers loading, operation, unloading and clearing, as well as disassembly and cleaning of multiple common firearms of the aforementioned time periods. Anything helps!
