前文所谓“并不罕见”，因为美军的M249出现过好几次这种问题，近些年光河马见过的视频就有3到4则——因为使用频次高，自动武器射击振动大，导致固定小握把（扳机组，阻铁所在位置）的插销磨损严重，出现断裂或脱位的情况。
具体用户对某一产品/部件到寿乃至超寿未加注意，继续使用的情况，也不是我们一家的问题。至于是不是生产质量问题（原材料、热处理工艺之类），导致插销提前到寿……反正研究美军的大佬一堆，也轮不到河马来说。
扳机组件都直接掉下来了，阻铁自然也无法工作——所以要么扯断弹链，要么等弹链打完，否则机枪会自顾自地一直打下去
机枪是一种以全自动射击为主的武器，各部位都是为了全自动射击工况优化设计的，供弹具弹容量又极大；所以武器一旦进入不受控的全自动射击状态，是极为危险的，要么打光弹药，要么扯断弹链，还得小心枪口指向。
因为立姿射击，失去小握把意味着失控，从抛出的可散弹链可以看到，此时机枪仍然在全自动射击，武器开始转圈圈，极其危险
副射手眼疾手快，扯断了弹链，终止了M249的不受控全自动射击，否则射手和射手身后人员都有生命危险（射手手里还捏着手枪握把）
M249的失控全自动射击问题，就是阻铁失效的另一种情况——直接“跑”了，用英语搜索这类视频，美国人有个非常形象也非常土气的描述runaway——反而用fail（ure），malfunction，out of control等关键词搜索还更费工夫。虽然口径不同，安装方式不同，但是M249这种让人胆战心惊的故障，和吓得安哥拉车长高举双手的Kord失控全自动射击，是一个原因。
The so-called "not uncommon" in the previous article, because the US military's M249 has appeared several times in this kind of problem. In recent years, there have been 3 to 4 videos that Guanghe has seen - because of the high frequency of use, the automatic weapon shoots vibration, which leads to fixing. The pin of the small grip (the trigger unit, the position of the resistance iron) is severely worn, and there is a break or dislocation.
It’s this bolt that has reached the end of life, causing the small grip to fall off. This bolt is the end of life, causing the small grip to fall off.
It is not our family's problem that the specific user does not pay attention to the product or component to Shou or even the super life. As for the quality of production problems (raw materials, heat treatment processes, etc.), leading to the advance of the bolt to the end of life ... anyway, the study of the US military's amnesty, but also the hippo.
The trigger assembly is directly dropped, and the iron is naturally unable to work - so either break the chain or wait for the chain to finish, otherwise the machine gun will continue to fight from the ground.
The machine gun is a kind of weapon with automatic shooting. All parts are designed for automatic shooting conditions, and the capacity of the projectile is extremely large. Therefore, once the weapon enters the uncontrolled automatic shooting state, it is Extremely dangerous, either to illuminate the ammunition, or to break the chain, but also to be careful to point at the muzzle.
It is also a case where the grip is directly dropped, and the grip is directly dropped.
Because of the standing shooting, losing the small grip means losing control. It can be seen from the thrown loose chain. At this time, the machine gun is still fully automatic, and the weapon begins to circle, which is extremely dangerous.
The assistant shooter had a quick eye and broke the chain, terminating the uncontrolled automatic shooting of the M249, otherwise the shooter and the shooter were in danger of life (the shooter also held the pistol grip in his hand)
Move the picture, feel how terrible the automatic control of the weapon is out of control, and feel how terrible the automatic control of the weapon is out of control.
The M249's out-of-control automatic shooting problem is another case of iron-resistance failure - directly "running", searching for such videos in English, Americans have a very image and very rustic description of runaway - instead use fail ( Ure), malfunction, out of control and other keyword searches are even more laborious. Although the caliber is different and the installation method is different, the M249 is a horrible fault, and the Kord out of control automatic shooting that scares the Angolan captain to raise his hands is a reason.
