Engaging claws (15) and (16) are provided in the upper right front part in the longitudinal direction of a barrel (8), and engaging claws (18) and (19) are provided in the upper left part thereof. A gunsight (10) is held in the barrel (8) by the engaging claws (15) and (16) or by the engaging claws (18) and (19). Consequently, the position where the gunsight (10) is mounted can be changed to a position where a player can easily use the gunsight (10). In addition, each of the engaging claws releases its engaged state by its elastic force to detach the gunsight (10) from the barrel (8) when a strong shock is given to the gunsight (10). Consequently, it is possible to prevent the gunsight (10) from being damaged or prevent the player from being injured. |
