We get to see another custom work by Renegade Cow with the gas operated KTW M1873 & UDL M1887 shell ejecting airsoft shotgun. The UDL M1187 is PPSH shell conversion whilst the KTW M1873 uses the Volante gas conversion kit for the KTW/Dong San M1873 series, the performance varies depending on the type of gas and the model used. When using green gas on the carbine model, the FPS (Feet Per Second) ranges from 350 to 400. On the other hand, when green gas is used on the Randal model, the FPS is slightly lower, ranging from 270 to 300.
