Got one of these for my Lage .22 mac 11 conversion, and it works awesome. Reached out to them about making an adapter for the Ciener .22 (Hohrein) mags for the AC556/Mini-14, and I got back a response pretty quickly, that they were interested in doing this. I volunteered the use of some of my mags, if they want to make an adapter for their speed loader. They seemed very interested. I would encourage you to check out their loader, and to contact them with interest in them doing an adapter for our application.
