I think it seems like a good option for people who want to get into the AR platform. Start with cheap plinking, and then when you want to you can replace the upper (which can be sent to your house with no FFL) and suddenly you have a full sized AR15 since the lower is a standard AR lower.

Since I already have a 15-22 I wouldn't go out of my way for another 22 AR, but if this was out there a year or so ago I definitely would have some thinking to do.
