KRISS Vector/TDI Vector

| Sunday, August 21, 2011 | 0 comments

The KRISS Vector series is a family of NFA and non-NFA weapons based upon the parent submachine gun design developed by KRISS USA. It was self-loading (semi-automatic) carbine i sa derivative of the Kriss Super V™ submachine gun. KRISS USA is formerly known as Transformational Defense Industries (TDI). KRISS Vector CRB/SO semi-automatic carbine utilizes patented SuperV™ operating system with light bolt that is connected to vertically sliding weight. According to the manufacturer, this system decreases felt recoil and minimizes muzzle jump, thus allowing for fast and accurate follow-up shots.

The Vector's barrel is in line with the shooter's shoulder as in the M16 rifle and German FG42, but also in line with the shooter's hand as with many target pistols. Combined, these factors reduce felt recoil and muzzle climb by eliminating the distance between the shooter's hand and the bore axis along with the action of the Super V Mechanism.

Fire control group is situated above the barrel. Folding cocking handle is located on the left side, and does not move when gun is fired. Manual safety is ambidextrous and is located just above the pistol grip. Feed is from 13-round Glock Model 21 magazines, but TDI company also designed an 17-round extension for said magazines for full 30-round capacity. Magazine is inserted into a housing, located in front of the pistol grip. KRISS Vector is fitted with two Picatinny type rails, one above the receiver and another below the barrel, and two additional rails can be installed on either side of the lower receiver, providing ample mounting space for all necessary accessories, such as laser-aiming modules or tactical flashlights. The upper rail can accept a variety of sighting devices, such as open or red-dot sights; lower rail is usually fitted with vertical fore grip.

Accuracy is not as good as the WWII era Schmidt Rubin K-31, but compared to other pistol caliber carbines it is pretty good.  Our test gun came in zeroed to point of aim at 25 yards, which is point blank range for the cartridge. I was easily able to keep 5 rounds within 2 inches at this distance. Other .45 caliber carbines, from the “Grease Gun” to the Thompson to the MAC-10 are considered “spray and pray” guns.  With the recoil and muzzle climb advantages of the KRISS and the actual physical accuracy of the gun, even rapid fire or possibly even full auto aimed fire is realistic.
