USAirsoft does some explaining and debunking in this episode covering the new Krytac KRISS Vector GBB SMG... "The announcement of the new gas blowback Krytac Kriss Vector has everyone talking about facts and stats they really don't know about so let me settle the disputes and clear up some misinformation by actually asking Krytac for myself the questions the community has been asking.

Keep in mind that the gas blowback Vector you see in this video was a prototype and not the full release model."
