[Lord of Rebirth]

Ok so I know the first game is old enough that a thread on it might be pages back in the search but i didn't see any threads on the first page so I'm hoping this is new enough not to be annoying.

What I kinda wanna do is totally recreate the whole arsenal available in the first and second game a la airsoft. I also wanna come up with a workable zombie sim game but that is another matter. The think I need help with is either identifying the guns or determining which available airsoft gun would be best to use as a base. The M16 is obvious enough and I already have one of them but I'm wondering what would be best for things like the hunting rifle and what specific type of AK-47 is the best match?
