KRISS Vector (FREE)

# About The KRISS Vector is a series of weapons based upon the parent submachine gun design developed by the American company KRISS USA, formerly Transformational Defense Industries (TDI). They use an unconventional delayed blowback system combined with in-line design to reduce perceived recoil and muzzle climb. # Design The Vector uses an articulated mechanism referred to as the "Kriss Super V", which allows the bolt and an inertia block to move downward into a recess behind the magazine well. The theory is that at the end of this travel, the energy is transmitted downward ratand. This is intended to reduce muzzle climb when combined with the off-axis bolt travel, though it also greatly raises the sight line in comparison to the bore axis. The initial prototype model by TDI achieved a rate of fire of 1,500 rpm, though this was brought down to around 1,200 rpm on the production models.
