The invention discloses a live weapon firing training system and a manufacturing method thereof. The live weapon firing training system comprises a bottom box fixedly arranged on the ground; a middleopen cavity with an upward opening is fixedly formed in the bottom box; a side cavity is formed in the left end wall of the middle open cavity in a communicating mode; a connecting cavity is formed inthe left end wall of the side cavity in a communicating mode; a side connecting cavity is formed in the left end wall of the connecting cavity in a communicating mode; the left side of the side connecting cavity is provided with an open cavity located in the bottom box and provided with an upward opening; a conveying machine driven by a motor is rotatably arranged in the open cavity; prepared foam is arranged on the upper end face of the conveying machine in an abutting mode; driving wheels which are vertically symmetrical are fixedly arranged on the upper and lower end walls of the side connecting cavity; and symmetrical driving wheels which are driven by the motor and are vertically symmetrical are fixedly arranged in the upper and lower end walls of the side cavity. The live weapon firing training system is simple in structure and convenient to operate, the efficient shooting recording process is achieved in moving projection and slow recording modes, meanwhile a disposable material is quickly replaced through a convenient and quick replacement structure, and thus the working efficiency of the live weapon firing training system is improved.
