Geonox Airsoft gets his turn to review an airsoft version of the Russian MP5, the Arcturus PP19-01 Vityaz AEG... "Here we look at the Arcturus PP19-01 Vityaz. It is an electric airsoft (S-AEG). Highlights are the powerful high-torque motor, the mosfet, the spring quick-change system, the microswitch and the rotatable hopup. And the foldable shoulder rest is ideal for transport or when things are tight."
