There is no doubt that KRISS USA is up to some interesting things. For example, the Vector Gen II CRB is a pistol-caliber carbine in the company’s line that is built around KRISS’ rather unique operating system. As a non-NFA firearm, this 16” carbine boasts flip-up sights, Picatinny rail and feeds from Glock pistol magazines. Interestingly, the Vector Gen II allows for easily swapping upper receivers between 9 mm Luger, 10 mm and .45 ACP. Watch this week’s video hosted by Kelly Young to learn more about the Vector Gen II.
