The Beretta Mx4 Storm

I have a Beretta Cx4 Storm in .45 and absolutely love it. Beretta released the Cx4 Storm as a "patrol rifle" (the label given by police for rifles incorrectly called "assault rifles" by anti-gunners, it makes the polices' rifles sound less scary) and shares magazine commonality with similarly chambered Px4 Storm pistols. I've always been curious why Beretta hasn't released a select fire version of the Cx4 Storm as it would make a sweet little submachinegun. After long last they have released one, the Mx4 Storm.

I think it goes without saying that I want one. Sadly as a lowly peasant I can't legally own such a rifle.
