Description of the Invention (3) The present invention relates to a light weapon and ammunition, which can be used to modify automatic light weapons for training purposes. More particularly, it is an automatic pneumatically actuated weapon that can be modified to shoot low energy training ammunition in a rebound mode and the training ammunition. 4 In military or police light weapons applications, almost all of the ammunition used is for training. However, normal ammunition is not appropriate for some training purposes. Another known training ammunition, disclosed in U.S. Patent No. 5,359,937, can rely on a special design designed to provide a periodic cycle for seat-actuated or pneumatically actuated automatic or semi-automatic weapons with appropriate modifications. A low-energy bullet, while firing a low-quality projectile. An advantage of low-energy training ammunition is that it has a shorter range and lower penetration than standard ammunition. This allows the use of smaller and substandard ammunition, as well as the use of smaller and less secure shooting ranges as training facilities. If standard ammunition is inadvertently used in these facilities, it may cause unexpected dangers due to the increased impact and range of the standard ammunition. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) The combination of the aforementioned training ammunition and some modifications in weapons can be performed through a pure blow-back action And exert normal recoil and shell ejection action. This system provides effective close range intensive training when firing properly labeled bullets. This system improves trainees' use of their actual weapons in simulations, such as counter-terrorism campaigns, meat wars, trench sweeps, jungle battles, street fights, and exercises to protect dignitaries. The reality and training value of interactive situational strategy training. 24 Take shooting low-energy ammunition as an example to enable 9-mm automatic or semi-automatic weapons. -3- This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm). 482888 Economy System A7 B7 V. Description of the invention () Modifications required for a cyclic cycle generally include replacement or modification of the barrel. Depending on the relevant weapon, sometimes one or two other components need to be replaced or added. In addition, because the caliber of the replacement training barrel may be smaller than the diameter of the projectile of the standard 9Γmm ammunition 4, these modifications can also be used to increase safety. If an attempt is made to insert a standard bullet into such a gun converted to a light weapon for training, the barrel of the gun cannot normally accommodate a standard projectile. This ensures that such modified weapons cannot fire standard live ammunition. 8 Other caliber light weapons, such as 0.45 mm pistols and 5.56-mm automatic rifle guns, can also be converted to use similar barrels used in the aforementioned 9-mm retrofit handguns to fire this low-energy training ammunition. . When firing standard ammunition, because of its abundant energy, many military 12 weapons must lock the barrel to the slide (in the case of a pistol) or lock while the breech is still closed while the barrel is moving backwards. Onto the bolt holder assembly (in the case of a pneumatically actuated rifle), and the locking time must be long enough to allow the projectile to leave the muzzle. This allows the pressure in the barrel to be lowered when the breech is opened, in order to extract and eject the fired cartridge case. There is a locking mechanism that first attaches the barrel to the sliding plate or bolt rack assembly during the first part of the recoil, and then usually releases the sliding plate or bolt rack assembly by means of a cam. When the lock is unlocked, the slider or bolt holder assembly will continue to move backwards by 20 movements until the shell of the shot bullet is ejected, and then return to its ready-to-fire position under the influence of the re-entry spring, so that Hold the next bullet of the magazine and load it. The training system must delete this barrel locking mechanism.

This can be achieved simply by changing the barrel of the barrel assembly on the upper part of the barrel and modifying the barrel of the barrel assembly and removing the locking mechanism. Although this design can ensure that the live ammunition cannot be fired from the modified weapon, it is costly and inconvenient for the user because of the many weapon components involved. 12 Another way is to modify only the bolt / bolt holder assembly so that the upper part of the gun holder and the lower part of the holder are not in contact. In this way, as long as the existing bolt / bolt holder assembly is replaced with a training bolt / bolt holder assembly, the weapon can be quickly converted to shooting low-energy training ammunition. Therefore, the object of the present invention is to provide a weapon configuration that can be quickly and easily converted into a training configuration without modifying the upper gun barrel assembly or the lower gun holder assembly. However, because the standard 5.56 mm barrel is part of the 20-piece pipe grabbing assembly on the upper part of the gun frame, this means that the live ammunition cannot be loaded. Therefore, if this approach is to be accepted from a safety point of view, it is necessary to include a mechanism in the design of the combination of the peg holder assembly for training and the low-energy bullet, so that it can be converted into a 5.56 mm weapon for shooting training. It can prevent the firing of live ammunition exactly. 24 Therefore, another object of the present invention is to provide a paper size suitable for M16Α2 (please read the precautions on the back before filling out this page) Order-5-482888 A7 B7 V. Description of the invention (Employees of Central Bureau of Standards, Ministry of Economic Affairs Modification system for pneumatically operated weapons represented by the Consumer Cooperative Rifle and Carbine series, so that training ammunition can be fired safely. At the same time, if a live ammunition is accidentally loaded during a training exercise or exercise, it can also be used accurately. It cannot be fired. The general form of the present invention will be described first, and then specific embodiments will be given in conjunction with the drawings to explain its implementation. These embodiments are only used to explain the principle of the present invention and its implementation. Related to the present invention The broadest and more specific form of the will be further explained and defined in the scope of each patent application. The present invention mainly refers to the Colt M16A2 rifle and carbine series, and has been modified to shoot like the United States Pneumatically actuated automatic weapon for low-energy training ammunition disclosed in Patent No. 5,359,937. In addition, no additional modification is needed for the weapon, only The training of the bolt with a notch end 12 The present invention is applicable to all cases where the bolt / bolt holder assembly is used to replace the standard bolt / bolt holder assembly. The reason is that the present invention aims to provide a modified light weapon A suitable training bolt, wherein the training bolt has a notch through which the striker can pass. The far notch is sized so that the bottom end of the standard bullet can not hit the striker. However, the The size is set to accommodate the bottom end of the training ammunition, so that the detonator of the training bullet can hit the firing pin. The shape of the notch and the training bullet can be selected to reduce the diameter of the notch so that the standard bullet cannot be made. But the bottom end of the training bullet can be accommodated with a smaller diameter. Alternatively, the notch can be provided with a protrusion at the bottom to prevent the bottom end of the standard bullet from entering, but the training bullet However, a complementary notch can be provided at the bottom end to cooperate with the convex portion. Therefore, training bullets can be engaged for firing, but standard bullets cannot. The same size of this paper is 4 8 16 20 24 Choi CNS) A4 specifications ((Please read the back first Please fill in this page again for further attention), v Yikou-6- 482888 A7 B7 V. Description of the invention () Ground, the edge of the training bullet and the matching front notch of the training bolt can be set in a circle in size Some other shape than the standard. When modifying M-16 light weapons, the standard striker, extractor and 4-pin latch can be retained. This new training bolt / bolt holder assembly can be used in the following ways Omit the barrel locking equipment of the standard weapon: (1) Replace the bolt with a simple cylindrical hole that can be fixed to the training bolt holder with a standard cam pin to pass through 8 grooves in the cam groove of the frame; and (2) removing air holes. As a result, the bolt locking flange cannot be rotated and engaged with the barrel extension in the ready-to-shoot or closed position, so when the low-energy training ammunition is fired, the modified weapon Acts in pure rebound mode. In addition, because there is no locking action, you can choose to retain or not retain the bolt locking projection 12 edge. The bullet-engaging end of the bolt of the M-16 type light weapon is provided with a notch. Generally, the edge of the bottom end of the standard live ammunition will snap into this notch and be clamped on the edge and the extractor that is caught in the extraction groove. In this case, the detonator face of the bottom end of the bullet will flatly bear against the flat bottom of the notch of the bolt, adjoining the needle tip of the retracted striker located inside. When the trigger is pulled, a striker drives the striker forward into the notch area and strikes the detonator, causing the weapon to fire. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) 20 However, because the diameter of the bottom edge of the training bullet has been reduced, the notch at the front end of the bolt is not large enough to make it impossible Holds 5.56 mm standard live ammunition. In addition, since the depth of the notch is much larger than the distance that the striker moves into the notch, the needle 24 of the striker and the detonator are not in contact after the striker is pushed into the notch. As a result, the bullets will not fire, and the modified Wuben paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210X297 mm) 482888 A7 B7. 5. Description of the invention () The device will not allow the user to inadvertently fire the standard live ammunition. risk. In addition, the training bolt / bolt holder assembly provided by the present invention can be freely reset as part of the rebound cycle operation, so that the weapon can be reloaded with 4 bombs. This kind of rebound operation can be achieved by using a telescopic elongated cartridge case as disclosed in U.S. Patent Nos. 5,359,937 and 5,492,063. For example, the low-energy training ammunition disclosed in U.S. Patent No. 5,395,937 can be made in the same 8 form of a 5.56 mm shell, except for the diameter of the edge of the bottom of the shell. However, this diameter can be reduced to a reduced diameter that allows it to fit into the training bolt. Therefore, the training ammunition can be properly engaged in the notch provided by the training bolt, and at the abutment and path of the retracted needle tip of the firing pin, the bottom end of the training ammunition should be flat against the notch. bottom. In this configuration, when the firing pin is activated, the firing pin will strike the detonator in the normal way, causing the weapon to fire. The telescoping of the bullet lengthens the rebound cycle of the executable weapon.

Invention Description () and the four major groups of typical rifles used in the carbine category. · Upper gun barrel assembly 1, bolt / bolt holder assembly 2, gun Lower frame butt assembly 3, and magazine 4. According to the present invention, a conventional weapon can be converted into a training configuration by only changing the bolt / bolt holder assembly 42, for example, firing a recoil-actuated bullet, such as disclosed in US Patent No. 5,359,937 or No. 5,492,063. Low-energy training ammunition (the former is the training bullet 21 shown in Figure 8A). 8 The second picture A and B shows the conventional bolt 5 which is part of the conventional bolt / bolt holder assembly 2-part. The bolt 5 includes a locking hole 6, a gas seal 7, a bolt locking flange 8, a front end notch 9, an ejector 10, a striker hole 11A, and an extraction member 12. The diameter of the front notch is indicated by the letter A. 12 The third one shown in figures A and B is a training bolt 13 of the present invention in which the conventional bolt 5 is modified. Since the training configuration is not pneumatically actuated, the air seal 7 has been removed to reduce manufacturing costs. As for the locking hole 6, the bolt locking flange 8, the ejector 10, the firing pin hole 11A, and the extraction members 12, 16 are all the same as the user. However, the training notch 14 is different from the conventional notch 9, and its diameter is replaced by the letter B and is about 0.020 inches smaller than the conventional diameter A (ie B < A). (A picture) settings vary. 20 The one shown in the fourth A is a conventional bolt holder 15 which belongs to another part of the conventional bolt / bolt holder assembly 2 and includes a cam groove 16 and an air hole 16A. The one shown in FIG. 4B is a conventional cam latch 17. During the assembly of the conventional bolt / bolt holder assembly 2, after the bolt 5 is inserted into the bolt holder 15 24, the cam latch will penetrate the bolt. Cam groove 16 and gun bolt of frame 15-10- (Please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) 482888 A7 B7 V. Description of the invention () 5 lock holes 6. The fifth figure is a training bolt holder 18 of the present invention in which the conventional bolt holder 15 is modified. Since the training configuration is not pneumatically operated, the air holes 16A have been removed to reduce manufacturing costs. In addition, the conventional cam groove 16 has been replaced by a locking hole 19 instead. When the training bolt 13 is inserted into the training bolt holder 18 to form the bolt / bolt holder assembly 18A shown in the sixth figure, the locking hole 6 of the training bolt 13 and the training bolt holder 8 are formed. The locking holes 19 of 18 are aligned so that the cam pins 17 can pass through these locking holes 6 and 19, so that the training bolt 13 is firmly fixed to the training bolt holder 18. In addition, the striker 20 is also shown to include a needle tip 11. The seventh one shown in Figures A and B is a 5.56 mm standard bullet 23, and its 12 includes a standard detonator 24, a bottom edge 25 and an extraction groove 26. The diameter of the edge 25 is indicated by the letter C. Printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) The figures in Figures 8A and B are disclosed in U.S. Patent No. 5,359,937, and are very different from conventional bullets 23 Training bullets 21. It doesn't matter if the detonator 24 is different from the training detonator 22, but the extraction grooves 26 for the two bullets are the same. As shown in the ninth figure of the bullet 21, the shell sizes of the two seed bullets 21 and 23 are set to allow them to be loaded and fully contained in the barrel portion 35 of the barrel 34 of the light weapon. However, the diameter D of the edge 20 of the training 20 is slightly smaller than the diameter of the conventional edge 25 (that is, D < C), and this difference is about 0.020 inches, depending on the diameter B of the notch 14 of the training bolt 13 (No. Three B)). The purpose of this difference in diameter is to prevent the recess 14 of the training bolt 13 from accommodating a conventional system 24 bullet provided with a conventional edge 25. -11- This paper size applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm) 482888 A7 B7 V. Description of the invention () After the conventional M16A2 weapon was modified to shoot low-energy ammunition 21, because only the training bolts were used The 18A / bolt holder assembly is different, so during the training session, 5.56 mm solid ammunition 23 may be accidentally loaded into the barrel of the training 4 weapon. An object of the present invention is to ensure that weapons modified for training do not fire standard bullets. The ninth and tenth illustrations show the manner in which the present invention cannot fire live ammunition. Yinfan, a consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) As mentioned earlier, the diameter of the notch 14 of the training bolt 13 (diameter B in Figure 3B) And the diameter 27 of the edge of the training bullet 21 (diameter D in the eighth B) are slightly smaller than the corresponding diameters of the conventional bolt 5 and the 5.56 mm ammunition 23 (diameter A and seventh in the second B) Diameter C in B). In addition, the diameter D of the edge 27 of the low-energy training bullet 21 is made to allow the bottom end 28 of the low-energy training bullet 21 to fit into the diameter B of the notch 14 of the training bolt 13 and be caught on the edge 27. The extractor 12 that is snapped into the extraction groove 26 is clamped there. In this case, the bottom end surface 28 of the detonator 22 will flat against the flat bottom of the notch 14 and the needle tip 11 of the striker 20 retracted inside it. When the weapon is actuated, as shown in the ninth figure, the striker 20 will rush forward, and the needle tip 11 will strike the detonator 22, thus igniting the detonator 22 and firing a low-energy training bullet 21. According to U.S. Patent No. 5,359,937, the low-energy training bullet 21 composed of the training shell 29, the training shell 30 and the training projectile 31, after firing, as shown in Figure 9A, will make the training use The elastic base plate 30 completely extends from the training elastic case 20. In this way, the training bullet 21 has been expanded vertically after firing. U.S. Patent No. 5,492,063 discloses another configuration that provides the same results. -12- This paper size applies Chinese National Standard (CNS) A4 (210X29? Mm) 482888 A7 B7 V. Description of the invention () As mentioned above, the diameter of the edge 25 of the 5.56 mm ammunition 23 (seventh The diameter C in the figure B) is larger than the diameter of the notch 14 of the training bolt 13 (diameter B in the third B), and has been designed to be snapped into the diameter 4 of the notch 9 of the conventional bolt 5 Inside. Therefore, if a live ammunition 23 is loaded to the upper barrel assembly 1 of the M16A2 weapon that has been converted to fire the low energy training ammunition 21, the diameter C of the edge 25 of the standard bullet 23 is as shown in the tenth figure It shows that it will not be caught in the diameter B of the notch 14 of the training bolt 13. 8 Because the depth of the notch 14 is about 0.125 inches, and the maximum distance that the striker 20 enters the notch is only about 0.025 inches, the needle tip 24 of the striker 20 does not touch the detonator 24 at all, so that the training bullet will not be fired, and This weapon will also clog, indicating a problem. 12 Eleventh A and B and twelve A and B are another method to prevent the detonator 24 of the standard bullet 23 from contacting the tip 11 of the striker. A convex portion, which is preferably semicircular (interruptible by the ejector 10), is added to the bottom of the recess 14 of the training bolt 13 so that the standard bullet cannot be fired. As shown in the eleventh sixteenth figures A and B, in this embodiment, the diameter B of the training bolt is restored to the standard diameter A. In addition, as shown in the twelfth figures A and B, a fully circular groove 33 is formed at the bottom end 28 of the low-energy training bullet 21, and the diameter D of the training bullet is restored to the standard diameter C. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) 20 If a live ammunition is accidentally loaded into the barrel, the bottom end of the live ammunition will be blocked by the raised portion 32 So that the tip of the striker 20 cannot touch the detonator 24, so it will not fire. On the other hand, if the low-energy bullet 21 is placed on the face, the 24 groove 33 of the bullet and the convex portion 32 are complementary in form and matched in size and shape, and will be caught in the recess 14 without hindrance. Therefore, when manipulating Wu-13- this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 482888 A7 B7 V. Description of the invention When the device is struck by the tip 11 of the striker 20, it will enter the firing. position. There are other methods that can also be used to prevent the firing of inadvertently loaded live ammunition. For example, the size of the edge of the training bullet can be made into a shape other than a circle, such as a hexagon, and the front end notch of the training bolt is set to match it, so the round standard ammunition cannot be loaded. Into the notch, as a result, the detonator cannot touch the tip of the striker. Therefore, the present invention relies on the dimensions selected for the recess of the training bolt. 8 The M16A2 rifle converted into a low-energy training ammunition has been tested. Many various 5.56 mm live ammunitions have been issued, which proves that the present invention can make live ammunition completely unfireable. Similarly, as disclosed in US Patent No. 5,359,937, 5.56 mm, many 5.56 mm low-energy training ammunition with a reduced edge diameter of 12 has also been fired with the same modification. The bolt / bolt holder assembly needs to be changed to produce a reliable and safe training weapon system and the inability to fire live ammunition. 16 In addition to the M16A2 rifle, this invention is also applicable to all light weapons that have been modified to fire low-energy ammunition and have the safety feature of being unable to fire live ammunition. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) The above examples are only used to illustrate the present invention, not to limit the scope of the present invention. Various modifications or changes that do not meet the spirit of the present invention fall within the scope of the present invention. -14- This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) 482888 A7 B7 V.
