Just to be clear: the carbine has a permanently-attached “muzzle break” that’s actually a baffle stack. You can buy the MPX, file your NFA paperwork, pay your stamp, and when it clears in a few months, you just drop on the silencer shell, screw it in tight with the endcap, and now your MPX is integrally-suppressed.

They’re going to sell shitloads of these.
