摘要： PURPOSE:To obtain such an effect as if the amount of gunpowder is increased although a model gun is safe as usual, by giving power to a powder smoke gas out of a muzzle without increasing the gunpowder. CONSTITUTION:A hole 3 for a barrel 1 is perforated near a muzzle 6 of the burrel 1, which is at the side of a gunpowder chamber, and a gas pipe 4 is fastened to the hole 3. A complete member wherein the barrel 1 is integrated with the gas pipe 4 is fastened to a model gun. At that time, the model gun is so composed that a high-pressure gas is sent into an entrance 5 to the gas pipe, that a powder smoke gas is sent into the muzzle 6, and that these gases do not flow upstream. However, it is necessary that processing being based on usual model gun regulations is done for a muzzle 2. Furthermore, it is necessary that a powder smoke gas-generating mechanism for the model gun main body and a high-pressure gas-jetting mechanism therefor are at a level being based on the usual gun regulations. In this way, such an effect as if the amount of gunpowder is increased although the model gun is safe as usual, can be obtained.

摘要： PURPOSE: To block bending vibration of weapon barrel at the time of firing by arranging a ring type inertia body concentrically to the axis of barrel while being supported thereat by a leaf spring. CONSTITUTION: First ring 23 having a hole 24 and a second ring 25 having no hole are arranged between both discs 17, 19 with the rings 23, 25 having identical inside and outside diameters. The hole 24 is inserted with a compression spring 26 having one end supported on the bottom of a blind hole 24 and the other end supported on the second ring 25. Several pins 27 are inserted into the first disc 17 with one end being supported by the second disc 19. Each pin 27 extending in parallel with the axis of barrel is secured with a leaf spring 28. Each leaf spring 28 surrounds the pin 27 over one half inner circumference thereof while being supported on an adjacent pin 27. One end of the leaf spring 28 is located on the inner surface of the first ring 23 which forms an inertia body.
