Yup. I even have still in packaging spare Butler Creek Steel lips banana mags for the 10/22. The package (from before the Charger was released, which was 2007 or 2009) from 2004 or so says "designed and fits Ruger 10/22". No mention of Charger as it wasn't invented yet (at least retail availability).
Yeah, that one is strange.
This may not be the best methodology but I just look at what is currently legally available for purchase in stores to determine how safe it would be to own it. But even then there is a slippery slope, as lawyers Ian Runkle and Ed Burlew point out, with the LAR15 mags, which are still available through many retail channels for purchase. Designed for LAR15 pistol but fits many AR-platform 5.56/.223. Mr. Burlew even mentioned in a post he has had clients who have been charged with having these - and while they were ultimately cleared it court, it was after significant time and legal expense were expended.
My understanding of AICS was that they were designed exclusively for bolt action precision riles. It would certainly be interesting if they fit into anything else.
