Wasnt excited about the 9mm that much. Still range toy. Wasn't excited about this at all until seeing this video. Guess it is actually fairly unique/interesting. Next time I want a fancy AR this might be top of the list. Course with wanting the MDR and it's multi caliber, not sure what good this would be unless I make some wanna be DMR with a longer barrel. Otherwise even sbr'd be no more compact than the MDR really. (But seems great if your anti bullpup or other kinda unproven stuff.)
