Here is a video from a Discovery Channel documentary. I posted a similar video about the P09 pistol. Well here is another one but this time about the CZ Scorpion Evo3. The video has the same formula as the P09 video. They show the barrel manufacturing process then move onto assembly. They even throw in a segue video clip of the siege on the Iranian Embassy in London, England. Again Discovery Channel throws in information that has nothing to do with the firearm being discussed. That siege was on April 30, 1980. 20 years before the Scorpion Evo 3 was even conceptualized. So ignoring that section the end is rather interesting seeing the torture testing of the weapon in water submersion and mud.
