Umarex T4E HDR .50 Co2 Revolver. The HDR 50 is a revolver with visible – Scopes and Barrels

  Umarex T4E HDR .50 Co2 Powered Revolver   HDR stands for "home defense revolver". That’s because even in Germany – Umarex’s place of birth – self-defense laws are very strict when it comes to "real" weapons, so alternative tools such as capsicum sprays or non-lethal guns such as this Umarex T4E HDR are very popular.
