Bill, your post confused me at first, and I had to read it a few times until I understood it. On my first reading, the situation wasn't immediately apparent (i.e., several RRA models are listed, but none of them actually had the listed model name marked on the receiver).
I think that the second bullet item ("Some newbie CA FFLs [...]") should be moved later in the posting, so that the "above 'listed' items" are actually above it. On my first reading, it just seemed to contradict the first bullet item. I don't think that the "Some newbie CA FFLs [...]" makes sense until the reader has digested some of the other details (that is, unless they already know about RRA's lowers and listed rifles).
