A friend of mine has a complete (we think) parts kit for an old AR180 minus the receiver. I just saw that there's a model called the AR180B which I don't see listed on the Roberti-Roos list or the Kasler list, I only see the AR180. And, they're supposedly interchangeable for most of the parts. Supposing he could find a lower for one of these B models, and a fix the mag/bullet button it would this be a legal set up?
