He means an adapter to allow the Mini-14 to use Ar-15 magazines or LAR pistol magazines.
Many years ago I thought there was a mag avail. that worked in both the mini and AR. I think there was only a small catch that you replaced to change the direction from forward pressure to release mag to sideways movement,darned old age can't remember who made it though---@ 20yrs ago last time I heard of such a thing
What is really needed is a "Ruger Charger" type pistol with mini14 action

I've got an old SIR catalogue somewhere that has those mags listed in it. Apparently, it was designed to work in the AR-15, Mini-14, and AR-180. I haven't really heard how the reliability was, though.
