Re: will a ax308 mag fit a ax aics ??
You'll have to have the action modified. The AW and AX rifles have a double set of feedramps (like an AR-15), whereas 700s have a single feedramp for use with the AICS mags. The AW/AX mags are double stack whereas the AICS are single stack/feed into the action.
If you're doing some research, you'll commonly see the modification referred as an AW magazine modification vs an AX magazine.
