Is anyone familiar with this carbine? I have the chance to pick up a used 9mm version with the top/sides/bottom rail, a vortex strikefire and like 5 20rd mags for $700. I have heard good things about reliability and accuracy. And im starting gathering equipment to reload 9mm. Just lookin for some thoughts... The first time i saw one of these i thought ewwwww but now i see it as a pretty nice package. Is it true its a cash and carry gun in MD?
