Experience one of the most innovative developments in modern firearms technology with the patented KRISS Vector Platform. At the heart of each Vector is the Super V Recoil Mitigation System. This unique operating system redirects energy down, and away from the shooter, which eliminates felt recoil and muzzle climb. The KRISS Vector GEN II is the next evolution of the Vector platform, taking it from a firearm into a multi-caliber weapon system and is compatible with the ubiquitous Glock magazine. Changing between calibers can be done in seconds, without any tools. The KRISS Vector GEN II is more ergonomic with a redesigned trigger, a short throw ambidextrous safety lever, and a more comfortable pistol grip. The KRISS Vector SBR is a NFA controlled short barrel rifle with a 5.5” barrel for the attachment of suppressors. The fixed KRISS M4 style stock allows for a wide range of adjustment to fit any user. Additional standard equipment on the KRISS Vector SBR are the flip sights, full length picatinny top rail, lower picatinny accessory rail, and a Glock magazine. The SBR is an NFA controlled item.
