I've got a atlasworxs bottom metal on the way now I just need to find some AI mag for it. What's the difference between the AX/AW/AICS mags?

Need a few for a 260 build

AW mags are a doublestack, double feed setup. They require a specific magwell cut on the action.

AX mags are specific to the AX chassis system

AICS Mags typically fit most bottom metal setups. They are a single stack single feed setup and are the standard mag for Badger, Seekins, APA, etc... bottom metals.

Thanks TMR, that's what I figured.

AICS is what you want for a 700 action unless you have the feed ramp modified, then you could go AW if you want a shorter mag with equal capacity.
