Rusia ha presentado un fusil compacto del tipo \u201cBullpup\u201d, especial para combate urbano y en calibre 12.7x55mm<\/strong>. Emplea un cartucho de dise\u00f1o especial, que utiliza el proyectil original de las Ametralladoras calibre .50, pero en una vaina de paredes rectas y de menor longitud. Este proyectil que es disparado a velocidades subs\u00f3nicas, tiene menor estampido de boca, menor retroceso y una combinaci\u00f3n de baja velocidad y gran masa, que entrega una enorme cantidad de energ\u00eda en el blanco. Con un alcance eficaz de hasta 300m, los beneficios son m\u00e1s energ\u00eda cin\u00e9tica en el blanco y menores riesgos de sobrepenetraci\u00f3n.<\/p>\n

Russia has a rich history designing exotic bullpups<\/a> in variety configurations and calibers. While most of those Soviet designs are forty or more years old (and were never standard issue), Russia does have several bullpups in their armories that fill very specific niche roles. These two platforms are optimized for urban and close-quarters combat\u2014 and fire enormous .50 caliber rounds to boot. Here are two highly-specialized Russian bullpup platforms.<\/p>\n

First the round. The 12.7x55mm STs-130 cartridge is massive\u2014 the same diameter as the .50 BMG round used the M2 Browning machine gun<\/a>. While the M2 is a crew-served weapon, meaning there is usually two or more people needed to operate the weapon, the 12.7x55mm STs-130 cartridge is not. Despite its enormous caliber, the STs-130 is used in individual small arms.<\/p>\n

The case is conventional brass, although it is a straight wall cartridge, an unusual feature in modern rifle ammunition, more akin to ammunition used in revolvers. This means that the brass case does not have a bottleneck where the bullet is seated, but rather is the same diameter around the base and the neck. Generally speaking, this result is less pressure in the case when the primer is struck, and less pressure behind the bullet during is movement through the barrel.<\/p>\n

Generally, this would be a disadvantage\u2014 when would a slower-traveling bullet have an advantage over a faster traveling bullet?<\/p>\n

First: when silence is needed. The STs-130 is subsonic and therefore much quieter than conventional supersonic ammunition. When coupled with a suppressor, there is a marked difference in noise.<\/p>\n

Additionally, this heavy slow-moving bullet is optimized for massive<\/i> stopping power\u2014 without risking over-penetration. In a tight urban or indoor environments, collateral damage can be caused by stray shots passing through walls, vehicles, or people and causing unintentional damage. Not so with the STs-130, which deposits massive amounts of energy on target, without over-penetration.<\/p>\n

The STs-130 comes in several different varieties, with different bullets optimized for different platforms and purposes. <\/i>Variants include standard, armor-piercing, and even an increased accuracy round, reportedly made of solid bronze. Ammunition that can be fired safely in the VKS cannot necessarily be fired with ASh-12.7, as the VKS\u2019 ammunition is significantly longer and heavier, which could potentially cause feeding problems if it could even be chambered.<\/p>\n

Hand-held Artillery: <\/b><\/p>\n

Meet the ASh-12.7<\/a>.<\/p>\n

The ASh-12.7 is optimized for urban, close-quarters combat where space is at a premium, and range is limited by walls and buildings. It\u2019s compact design allows it to have a high barrel-to-length ratio. This allows for quick movement and greater maneuverability, although there are some shortcomings<\/a> to the bullpup design such as lower situational awareness and poor ergonomics for left-handed shooters.<\/p>\n

The rifle has two firing modes, semi and auto, plus safe. Because the ammunition is subsonic, effective firing range is a modest 300 meters or so, although this would not necessarily be a problem in close-range, urban environments.<\/p>\n

The rifle features a large multiple-baffle muzzle brake to help control recoil, especially during automatic firing. It can also be equipped with a silencer, further reducing the subsonic ammunition\u2019s acoustic signature. One variety of ammunition for the ASh-12.7 is a double, or duplex round<\/a>, which is essentially two bullets stacked one on top of the other.<\/p>\n

VKS Sniper Rifle:<\/b><\/p>\n

Also a bullpup design, the VKS is optimized for close-quarters, urban combat environments. Interestingly, this rifle appears to be a straight-pull bolt-action, rather than a semiautomatic.<\/p>\n

Effective firing range is nearly double that of its .50 caliber ASh-12.7 cousin, reportedly<\/a> up to 600 meters\u2014 not bad for a subsonic bullet. The VKS is also equipped with a large silencer nearly the length of the entire barrel, similar to the VSS Vintorez<\/a>, or the AS Val<\/a>.<\/p>\n

Whereas those two platforms are optimized for penetrating standard-issue NATO body armor, the VKS makes use of specially designed ammunition to prevent<\/i> penetration. While the case for VKS ammunition is the same case used for ASh-12.7 ammunition, the bullets are much longer and heavier, and probably too long to load in the ASh-12.7 rifle. The heaviest loads are reportedly 76 grams or 1170 grains\u2014by comparison, the standard 5.56x45mm NATO bullet<\/a> weighs 4 grams or 62 grains. One of the loads is even machined from solid brass<\/a> for better accuracy.<\/p>\n

Close Quarter Killer:<\/b><\/p>\n

Short overall length, quiet, and massively powerful\u2014 seemingly the perfect small arms platforms for effective urban combat. It seems that Russian bullpups have staged a comeback, at least in certain close quarters operations.<\/p>\n
