Model: KV45CFD22UPC: 810237023259 Kriss didn't create the Vector platform to simply LOOK advanced. Inside the admittedly-cool exterior lies one of the finest firearm innovations we've seen in some time: the Super V Recoil Mitigation System. This unique operating system redirects energy down and away from the shooter, virtually eliminating felt recoil and muzzle climb. The low bore axis takes it a step further, ensuring that the recoil travels back, not up. Gen II: Back and Better than Ever. The Gen II refined many of the performance factors of the Gen I. Chief among them, better ergonomics thanks to a redesigned trigger, short throw safety lever, and more comfortable pistol grip. Other upgrades include a chrome-lined barrel, beefed-up barrel contour, improved fire control group, and a re-positioned fire / safe switch, among others. The Vector CRB is the non-NFA, semi-automatic, carbine variant with a 16" barrel. The Defiance stock provides a wide range of adjustment and length of pull. Flip sights, full length picatinny top rail, lower picatinny accessory rail, and a Glock magazine all come standard.
