The Remington, err, Freedom Group booth was huge! It was a very nice walk in arrangement of multiple vendors (Bushmaster, DPMS, AAC, etc).
They had a nice display of the RM380 with multiple versions to play with. In the exact same spot and arrangement as they had for the R51 two years back. That begged the question, of course, WTF happened to the R51? So I asked.
The rep. was a little embarrassed and said that the project was still active, however, that they had not fully worked out all of the problems (holy cow!) and that they would not release it (again that is) until they were all resolved. I offered my support of the concept (it felt great in the hands and a polymer lightweight +P pistols sub-$450?) but that I wouldn't be holding my breath. I do hope that they get it worked out, but from the looks of things - I got the impression that they just wanted to forget that it ever existed and move on.
I wasn't super excited by the RM380.
