This armorer’s manual is issued to the IDF for servicing of their TAR-21 assault rifles. It is an amazingly detailed resource for complete stripping, well beyond basic field disassembly. You will notice some difference between what is in here and what is in your civilian carbine. Primarily the automatic components, but also details like installing the M203 grenade launcher. This is however much more useful than standard documents when it comes to things like left-hand conversion, or removing the barrel.
