  • FIG. 30 shows the individual components of a reflection mechanism mounted on a barrel sleeve.
  • the barrel sleeve is provided with curly grooves 60 and vertical curly grooves 62 (see Figs. 31, 34, 35).
  • the reflection mechanism includes a reflector 56, a contactor 66, and a reflector spring 59.
  • Mentioned reflector 56 is made with side surfaces corresponding to the figured grooves 60, an opening 64 for accommodating the reflector spring 59, as well as a groove 65 located at the rear of the reflector 56 and configured to interact with the contactor 66.
  • the reflector 56 has a tooth 57 for interacting with the reflected sleeve (see Figs. 25-29, 35).
  • the reflector 56 by means of the tooth 57 for influencing the spent sleeve ensures its reflection outside the box through the extraction window 58 of the firearm.
  • Said contactor 66 intended for mounting the reflector 56 and spring 59 on the barrel sleeve 2, comprises an extended end portion 67 designed to interact with the vertical curly grooves 62 of the barrel sleeve, the size of the terminal extended portion 67 of the contact 66 being set smaller than the smallest vertical size figured groove 62 for reliable placement in it to prevent horizontal movement of the contactor 66 (see Fig. 31, 32).
  • the front end 68 of the contactor 66 is designed to be placed in the groove 65 of the reflector 56 to prevent its vertical movement (Fig. 32) and also has a protrusion 69, which is configured to enter the inner diameter of the coils of the spring 59 to prevent horizontal movement of the front end 68 of the contactor (Fig. . 32, 35).
  • the protrusion 69 extends along the entire length of the reflector 56 and enters the hole 70 in the head of the reflector (Fig. 36).
  • the groove 65 made in the rear of the reflector when interacting with the front end 68 of the contactor 66, keeps the contactor from vertical movement, but allows you to move in the longitudinal direction relative to the reflector to ensure its operation (see Fig. 32, 33).
  • the reflector 56 is fixed in the figured grooves 60 by means of a spring 59 located in the hole 64 inside the reflector to return the reflector to its original position, and a contactor 66 located in the vertical figured grooves 62, with in this case, the reflector may perform the aforementioned in connection with FIG. 25-29 longitudinal movement along the axis of the bore from the starting position at which it is extracted short sleeve, to the rear position when the long sleeve is extracted.
  • the hole 64 may be partially open so that the spring cannot fall out of the reflector, as shown in FIG. 30 and 31.
  • the assembly of the mechanism is carried out by putting the spring 59 on the protrusion 69 of the contactor 62, inserting the reflector 56 into the grooves 60 of the barrel sleeve 2 until it stops. After that, the front end of the protrusion 69 of the contactor 66 is placed in the hole 70 of the reflector 56, compressing the spring 59, while the back of the contactor 66 is pressed against the cylindrical surface of the barrel sleeve 2.
  • the present invention in each aspect is disclosed in relation to a smoothbore multi-shot firearm, in particular a smoothbore gun, automatic or semi-automatic action, but can be suitably adapted by a specialist for another type of weapon with the effect of increasing the reliability of the use of weapons with ammunition of different power.
