I for one would love to have one if they were actually made. But like has been said above, I would consider it a toy until proven otherwise because I really think the rimmed round would create a feeding nightmare as far as the magazine goes. Having said that, I disagree with the statement above about the magazine being wrong in the picture just due to the fact that the magazine is long and wide enough, but would require some form of insert which would act as the true magazine, while the standard AR mag body would just basically be an adapter to make sure the internal magazine was in the correct place for feeding. I think this would be an interesting concept, and doable, kind of along the lines of the Coonan Cadet 1911 in .357. Doable, but more of a playtoy with inherent limitations and problems that would limit it to range toy or hunting rifle status, at least in my book.
