AICS .223 Polymer Mags

Thanks, I have a V-Bull Precision for my Savage, it's a 308, and just out of curiousity I tried a mag, it was very tight going in, that's what got me wondering.
So if I get the Seekins BTM for a AICS "short action", that should "mate up" with my Stiller Tac 30 and my .223 mags?
