The KRISS Vector series is a family of weapons based upon the parent submachine gun design developed by KRISS USA. They use an unconventional delayed blowback system combined with in-line to reduce perceived recoil and muzzle climb.
The Vector's action, the so-called KRISS Super V System (KSVS), is an articulated mechanism which allows the bolt and an inertia block to move downward into a recess behind the magazine well.[not in citation given] The theory is that at the end of this travel, energy is transmitted downward rather than rearward. On return, however that downward force is negated by upward force. The Vector family of weapons is the first to use this action. .40 S&W and 9×19mm Parabellum variants were mentioned when the gun was first released, but are not currently offered or projected by the company. The firearm was designed to accept standard Glock 21 pistol magazines. When fired, the barrel axis is in line with the shoulder as in the M16 rifle, but also in line with the shooter's hand. This is intended to reduce muzzle climb when combined with the off-axis bolt travel.
The selective fire submachine gun variant, the Vector SMG features a 5.5 inch barrel, folding stock, flip-up Midwest Industries back-up iron sights (BUIS), Picatinny rails, and three-mode selective fire (single, two-round burst, full-auto).
- The 2-Round burst on the Vector was not included in Ghost Recon Phantoms, it only supports Auto and Semi fire modes.
- The Vector's magazine in Ghost Recon Phantoms are not depicted like the real life counter part, example: 10 round magazine = 20 magazine, 20 round magazine = 30 round magazine.
- The HLW-WB skin is included in the Halloween Reloaded: Complete pack.
- The Halloween version was released first on 22 October 2014.
- The Modmaster was mistakenly released on the 26 November 2014 for one day (then removed) along with the other IX (9) Series 2 modmaster weapons.
- The Modmaster version was released on 3rd of December 2014 (it was available ONLY to Infinite Pack customers before this date).'
