I have had them completely/totally apart apart on many occasions. But it has also been many years since I have done it. The one key thing I can remember is one of the screws that can be seen on the outside of the receiver must be removed "first" if you are taking out the the bolt, lever etc.
If you fail to take it out you get quite a few parts out of it but with them out you won't be able to get the screw out to free up the bolt and lever removal. You will have to reassemble the whole thing to get that screw out.
I can't remember which screw it is. And I don't have a 94 on hand to take a look. If you are at all mechanically inclined and have disassembled guns before you will be fine. Make notes and take pictures to help your memory.
Sorry I can't be more helpful as I never made notes, and digital cameras were not thought of when I was doing it.
