I believe that is all compiled code. I don't know of any way to decompile it, meaning to edit it you would need the source code and would have to compile that after making changes.

If your are trying to edit the weapons for CSS, you can just download the source code through steam, and open it with a C++ editor like visual studio.

I'm just speculating so don't take everything I say for fact, there might very well be a way to edit the weapon files without having to compile and do all that crap, but there isnt any other way that I know of
