I just found a site that offers lots and I mean lots of gun papercrafts. The guns at the middle are small and the ones at the bottom are big, maybe 1:1 scale. I'm not too sure though. The files come in lzh. I think you can open that using winrar. If not, you can download alzip, a free utility software that can open zip, rar and lzh. You will also need a pepakura viewer to open the model parts.
