因为光是准不能当饭吃
要回答为什么军方对M200不感兴趣这个问题，首先要说说为什么12.7口径的狙击枪近年来被大量采用，相比起7.62Nato的各类狙击枪，12.7口径的步枪在射程和弹道性能上的优势自不多说，更重要的一点是 大口径弹头在弹种上可选择的余地多太多 。
口径大，弹头大，带来的优势就是能往弹头里塞的东西多，自然也能折腾出更多的花样。
12.7,也就是.50BMG口径的各类弹种少说也有几十种，从穿甲弹（M2黑尖）到曳光弹（M1红尖）甚至穿甲燃烧高爆弹（没错，就是有这么多效果，Mk211）任君选择，自然在应对各类目标以及执行各类任务的时候都能“对症用药”。无论是打人、打掩体、打爆炸物、甚至是打轻型装甲车辆都没问题。
那么，M200的.408 CheyTac口径呢？
只有一种。
没错，一种，均质实心弹头。
M200精度是挺高，但是这个高精度得来并不是没有代价的，其中一项就是.408Chey Tac特制弹药，不同于寻常的军用步枪弹弹头结构，M200的.408弹的弹头 为纯铜弹头，只用一根铜镍合金的实心棒通过CNC 加工成形 ，而不是像传统弹头那样用铜被甲包裹其他材料制成的弹芯， 这样做虽然让弹头重量和重心的一致性达到了相当高的水平，但却使其在实战中的用途变得极为单一。
这种就相当于一块匀质金属的弹头，无论是穿甲能力还是对硬目标的毁伤能力都远远不如复合结构的各类传统弹头。 而改用传统结构的弹头的话，M200的精度比起.50的狙击枪又没有优势了。
让我们来总结一下：
M200作为一支和大部分.50BMG口径的狙击枪 差不多长、重、贵，但是却只能用来打人的存在。无人问津难道不是很正常的一件事么？
虽然CheyTac公司拼命地宣传，包括在电影《SHOOTER》和电视剧《THE UNIT》上作为道具出场，在COD6等游戏上露面，又上过《未来武器》这个著名的软广告节目，但还是没什么“钱途”。偶然会有爱好者通过CheyTac公司或EDM公司或THOR公司购买一把新枪，或在其他地方买一把二手枪。曾有人戏言，买这枪的人就跟每年被雷劈死的人一样多（但后来有人专门了解了一下在美国每年被雷劈死的人数统计，结果发现被雷劈死的人远多于买这枪的人）。 ——枪炮世界

现如今最好的轻武器通常都没法普及
很多比M200更应该得到普及的武器类型中最优秀的那一些，像手枪中的sig p226，步枪中的scar，都没有普及，因为太贵，选择低一级的或者维持现有的明显更划算。
和.408一样先进的子弹比如步枪里的.300blk，手枪中的10mm，也都没有普及，因为改了一种武器的口径，会牵扯到很多别的武器，否则，就要加重后勤负担。
美军的实力足够吊打地图上所有小朋友。谁还需要那么先进的轻武器，更何况，现有的轻武器也没有烂到要淘汰的程度。
人家现在用是什么，近距离有各种5.56的dmr，可以通用所有步兵手中的m16、m4弹药，中等距离有7.62的m24和m21，通用所有的m240. 远距离有12.7的巴雷特，通用m2hb。所以为什么要费劲去采用一种额外的弹药呢？不光美军是这样，基本上能大规模装备得起m200的国家也就北约那帮子，而他们的情况也和美军一样。
什么好就买什么，见什么爱什么只能成为另一个阿三，而像美军这样只用三种子弹就能满足几乎所有单位的需求才叫厉害。
1.子弹口径罕见、后勤麻烦；
2.用途单一，远距离打人；
3.价格昂贵。
以上三条足够枪毙M200了。
整体感觉M200更像纸面数据上优秀，但考虑到综合就需要好好考虑一下了。
补充一下：
除非新晋武器与现役的在重要性能上相比有天壤之差别，不然很难取代现有武器。而且即使有天壤之别，也要看情况，也不是一定就可以取代的。
戳靶玩具确实准的不行，为了精准牺牲了其他很多重要的东西，比如功能性。
但是军队里面有多少人能完全发挥出这把武器的极致，让它的精度物有所值呢？ 多数大头兵的操作恐怕连巴菲特黄金大炮阻的极限精（xin）度（yang）都发挥不出来吧。
来我们看看目前世界上的狙击记录还是 m82a1 (不是改良的m107)保持的 2815米 呢。等大家都差不多是这个水平了，再考虑列装m200不迟。
《澳洲每日电讯报》原文：
Here is one among hundreds of reasons why. Earlier this year a Commando sniper team was secreted in Helmand. Through binoculars at a distance invisible to the naked eye they spotted a group of Taliban. The soldiers having means of identifying targets went through a process of obtaining verification and permission to engage.
Two marksmen using Barrett M82A1 50 calibre rifles simultaneously fired. The bullets were six seconds in the air. One killed the Taliban commander. It is not known for certain which sniper fired the fatal shot.
While there have been no triumphant press releases, in the tight global Special Forces sniper community the shot is much discussed, because it seems certain to be a world record.
As the bullet yawed through the thin air on a windless morning, GPS aids measured the distance at 2815m . That amounts to 2 1/2 times the length of the Sydney Harbour Bridge. The targeted Taliban would not have heard the gunfire.
The previous world record achieved by British Corporal Craig Harrison occurred also in Helmand in November 2009. Firing from a distance of 2475m, Harrison killed two Taliban.
While British, American and Canadian sharpshooters are often celebrated the Australian Defence Force says nothing. When I sought to check this story I was politely told I could not be assisted.Fair enough. We are not talking about an Olympic event. An expert I did prise a few words from said that shooting at that distance beyond the weapons capability calls for luck, but it had still taken skill.
Delta Company of 2 Commando Regiment based at Holsworthy finished its tour months back. They are also not talking up what is seen as another day in the office.
All through southern Afghanistan the insurgency counts further costs. Since 2011 the Australian Special Operations Task Group has combined with the US Drug Enforcement Agency and Afghan National Interdiction Unit to conduct a counter nexus program with a devastating impact on the Taliban bank balance. There have been costs too. Private Nathanael Galagher and Lance Corporal Mervyn McDonald from 2 Commando were killed during a counter nexus mission in August.
DEA Regional Director Mike Marsac told me he sees no distinction between the drug lords and the Taliban. By their own choice the Americans forged a working relation with Australian commandos because they got results. The operations are timed to strike at the drug labs when the principals are in place and the farmers have been paid off. While you have heard little of it here, over there, hundreds of labs have been destroyed with billions of dollars lost to the insurgency.
Add to that the counter-leadership missions conducted almost daily by Australia's Special Air Service Regiment that keep Taliban leadership hiding out in Pakistan. You would hardly say they are winning.
But also there is no denying the Taliban strategy of waiting out the foreigners has proved more effective than the Coalition's efforts to operate a successful counterinsurgency. COIN as it is known, has become devalued in only a few years of assertive implementation. To prevail you must win the trust of the population. This was never likely when the population knew the foreigners would go before faith in their own government could build.The MTF, now surrendering their beat in Uruzgan has had a tough end of the mission. Protecting the population has meant feet on the ground and increased exposure to the Taliban's most effective weapon, the improvised explosive device.
In an already exposed environment an increase in green on blue killings by Afghan allies has accelerated their exit. While the remaining Afghan Kandaks will not patrol as effectively and in all likelihood negotiate more of an accommodation with the Taliban, it is time they took over.
Our withdrawal should not be seen as a failure. Uruzgan is a different place, with roads, schools, hospitals and the semblance of a functioning economy.The Australian SOTG will remain in Afghanistan until at least 2018. This is not good news for the Taliban. All through the hills and valleys there will be nervous discussion of lethal strikes, from nowhere.
不当家不知柴米贵啊！
军方预算有限啊！美军也是啊！钱多要一点就会被国会骂死啊，反对派喷死啊，反战人士游行啊。。。等等。
钱这么有限，再整整什么航母之类的大件。再给140w+的一支军队换这么贵还不好保障后勤的鸡肋。。。。
想想就心疼
世界上精度最高的狙击步枪——M200，为何美军却从不大量装备？
m200应该是一套狙击系统。
准头高并没有什么卵用。
目前世界最远狙杀记录，排名第三的狙击手用的是L115狙击步枪。
目标距离2475m，两发击毙两名机枪手。
也就是说.338Lapua Magnum武器也能做到2km外精准击杀了。
然而L115重量绝对不超过10kg，还能打汽车引擎。
那我为什么要拿一个重量堪比反器材，打起来却连穿墙都嫌侵彻力不足的武器去打人？
而且还是在有更好选择的情况下。
枪这玩意儿，一般来说广告吹得越响，东西越垃圾
吹牛吹到电影和discovery里的枪，9成9没有长期饭票，指望着一帮想装X玩的民间人士带去戳靶纸
这支枪唯一可以拿来称赞的就是让你能费更大的劲在你想像不到的距离做到你在600米就能轻松做到的事。所以才会没人愿意用。

比准比不过tac50，弹头是车出来的，还这么独，甚至比不过自己的.357。数据作假，遮遮掩掩，广告做的再好也只能骗骗财大气粗的小白去买。
M200好比一个去企业应聘的小伙子 面试官:特长？ M200:我数学计算能力全国第一，考试95分 面试官:哦。
高票引用强暴师姐的答案很全面的说了， 长、重、贵。
这货比M82A1还重一丢丢。。。
别听他们胡扯，一句话，相比同类产品，虽然精度好，但是后期保养和维修太贵了，整个狙击系统更是超级贵，所以大范围装备是不可能的，这是唯一的原因！
木桶
在COD6中，你一般只能用这枪和人在200米内玩近战，还是拉栓枪
