[灌水]俄国新式大口经狙击步枪——VSSK Vychlop

12.7毫米的VSSk（<em>Vintovka Snayperskaya Spetsialnaya Krupnokalibernaya</em> ——大口经特种狙击步枪）Vychlop（大概是译成“释放”）是俄国著名的俄国机械设计局（KBP）的最新力作。该枪大概是在2002年左右为满足俄国联邦安全局（FSB）的要求而设计的。它的第一次公开展示是在莫斯科INTERPOLITEX 2005 （大概是2005俄国国际警用装备展）上。该枪据称仅装备了俄国FSB主要从事反恐以及处理重要犯罪的特种单位。因此关于该枪的信息是少之又少，也就是展会上制造商那里得到的那些了。

<p>Vychlop狙击步枪是专门为需要寂静射杀任务准备的，估计它也是9毫米的VSS最好的换代产品。该枪主要对付的目标是车辆和有重防护的恐怖分子。</p><p>VSSK狙击武器系统的核心是特殊设计的12.7毫米的特种亚音速弹头（初速290M/S)该弹的具体数据不明，但全长是97MM——这要比俄制式装备的12.7×108弹（全长145MM）要短很多。该弹具有高精度、高侵彻力的特点。弹头重59克或者76克，精度百米1MOA。而侵彻力则达到完全可以在100米穿透俄标的5级（美国NIJ III级）防弹衣的水平。在200米也可以穿透16毫米的钢板。<br/>超大现在的BUG太多，回复一个帖子都要试N次！网速也不行。</p><p>郁闷。</p>

<p>其实这种.50口径特种消音弹药的概念并不是最近才提出的。早在上世纪90年代初美国弹药方面的专家J.D Jones就研制出一种12.7mm特种弹也就是.50Whisper。该弹是在.460马格农弹的基础上改短弹壳，加重弹头而制成的。这种弹药用于经过改装的带消音器的手动步枪上（比如温切斯特M70或者Sako TRG－S）这种弹药与前面说过的Vychlop用的STs-130 12.7mm弹药非常类似，二者都声称有1MOA的精度，有效射程600米。但是现在并不知道是否有哪家美国的执法部门装备了使用.50Whisper弹的步枪。而VSSk则是专为执法部门和军队特种作战设计的。</p><p>Vychlop安装的大型整体式消音器可以在运输、储存和维护保养的时候拆下来。该枪布局为无托式，有可折叠的的两脚架，抵肩板和腮垫都可调。机匣上有瞄准镜导轨，当然也有可折叠的机械式瞄准具作为备份。该枪是半自动的但具体采用什么动作方式还不清楚。另外，该枪弹夹容量为5发。</p><p>——“参数错误”究竟是什么原因啊？？</p><p>晕死。</p>

<p>好文，长知识了。顺便坐坐沙发！</p>

哈哈............首见啊！！

<p><b>Caliber</b>: 12.7mm special subsonic <br/><b>Operation</b>: semi-automatic <br/><b>Barrel:</b> n/a <br/><b>Weight</b>: 5 kg empty, less cope and silencer; 7 kg with scope and silencer, less ammunition <br/><b>Length</b>: 795 mm with integral silencer <br/><b>Feed Mechanism</b>: 5 rounds detachable box magazine. </p><p>12.7mm VSSK (<i>Vintovka Snayperskaya Spetsialnaya Krupnokalibernaya</i> - special sniper rifle, large caliber) "Vychlop" (Exhaust) silenced sniper rifle is one of the most recent creations of famous Russian Instrument Design Bureau (KBP). Developed in around 2002 on special request from Russian FSB (Federal Security Service, successor of Soviet KGB), this rifle was first show to general public only in late 2005, during arms exhibition INTERPOLITEX 2005 in Moscow. This rifle is said to be in use only by special elements of FSB, which conduct mostly counter-terror and high importance anti-crime operation. Information on this weapon is very scarce, so its description below is based on manufacturer's leaflets that were displayed at the same exhibition. Author plans to extend this article as soon as more reliable and extensive information will be available. </p><p>12.7mm "Vychlop" (Exhaust) silenced sniper rifle is developed for special operations that require silent firing and penetration much superior to that provided by <a href="http://world.guns.ru/sniper/sn20-e.htm">9mm VSS silenced sniper rifle</a>. Typical targets for VSSK Vychlop are cars, terrorists in heavy body armor or behind covers like car bodies or other thick covers. The core of the VSSK complex is specially developed 12.7mm (.50 caliber) reduced power ammunition that launches bullets at subsonic muzzle velocities of about 290 meters per second (~950 fps). Exact dimensions of the new cartridge case are not yet published, but the overall length of the new 12.7mm round designated STs-130PT&nbsp; is given as 97mm, significantly less that of standard Russian 12.7x108 HMG round (145mm overall length). Standard loading for this round is precision machined solid bronze projectile with pointed nose, weighting around 59 gram (910 grains) or 76 gram (1170 grains) "high penetration" bullet. Accuracy is claimed as 1 MOA at 100 meters range with precision bullets, and maximum effective range is given at 600 meters. High penetration bullet can defeat Russian Class 5 (US NIJ Type III / High-Powered Rifle) body armor at 100 meters or 16mm steel plate at 200 meters.<br/>It must be noted that the concept of dedicated.50 caliber silenced weapon with special subsonic ammunition is not new. Back in early 1990s noted American ammunition specialist J.D.Jones of SSK Industries developed a specialized 12.7mm round known as .50 Whisper. This round was based on shortened .460 Weatherby Magnum case, loaded with heavy, pointed low-drag bullet. This cartridge is intended for use in specially modified bolt action rifles (like Winchester Model 70 or Sako TRG-S) fitted with silencers. Ballistic properties of the .50 Whisper are very close to that of 12.7 STs-130 ammunition - both claimed to have accuracy of 1 MOA and decent effectiveness out to 600 meters or so. However, it is not known if any of US law enforcement agencies ever used .50 Whisper or similar guns, while VSSK was developed especially for law enforcement and military special operations use. </p><p>VSSK "Vychlop" rifle is fitted with large integral silencer that can be removed for storage, transportation and maintenance. Rifle itself is built using bullpup layout; it has integral folding bipod, and adjustable shoulder pad and cheek rest. Top of the receiver is fitted with scope rail, and rifle is provided with folding back-up iron sights. Apparently, this rifle is semi-automatic, but exact details of the action are unknown. Detachable box magazine holds five rounds of ammunition. </p>

呵呵，每次我的帖子都是看的多回的少，不过为了更多的同好能看到，还是本人自己顶顶吧。
