The 7.62 x 39 standard AK mag will not work. I think some people have tried modifying the .223 AK mags. Then again, if you look hard enough you can probably find some reasonably priced Galil Mags that will not be much more in cost than one of those .223 AK mags will. There were some adapters floating around for awhile which would allow you to put an AR-15/M-16 magazine in the .223 Galil. If you find them now, you will pay $100-150 for one. The AR mags are cheaper though, so I guess it works out in the long run. As for the .308 Galil, I have no idea if there are any possibilities for mag swapping, but I doubt it.
