The KSVK 12.7 is a heavy anti-material rifle designed by Russian for specialized Russian Army forces. The weapon is intended for disabling light military vehicles, penetrating fortified enemy positions and counter-sniping duties. Development of this weapon system began at the end of the 1990s under the guidance of ZID, formerly the Degtyarov Plant, makers of World War 2-era anti-material rifles. The Russian Army saw extensive experience in the decade with their two wars against Chechen rebels and the need for a capable and modern anti-material rifle was never more apparent. The KSVK 12.7 was initially known under the designation of ASVK and is based on the earlier SVN-98, an experimental anti-material rifle.

The KSVK 12.7, as its designation suggests, is chambered for the 12.7x108mm cartridge and operates from a manually-actuated bolt-action system that feeds a single round from a spring-loaded, 5-round detachable box magazine. The weapons weighs 12 kilograms sans any optics installations and features a length of 1,400mm with a barrel length of 1,000mm. The rear-fed nature of the magazine (rear of the pistol grip that is) categorizes the KSVK as a "bullpup" configured rifle design. Design of the receiver is essentially tubular with a shoulder stock added to the rear for additional support. The shoulder stock features a noticeable ergonomic curve and a bipod is fitted ahead of the receiver as standard. The pistol grip and trigger unit are mounted under the receiver at about the midway point in the design. A long, perforated muzzle brake caps the barrel to help retard the inherent effects of the massive recoil delivered from the firing of the powerful 12.7mm cartridge. The standard rifle design incorporates iron sights for the user but the weapon is designed (by way of an accessories rail) to accept common day/night optics as needed. These optics are fitted just above the pistol grip unit.

The KSVK 12.7 is currently in service with a select group of Russian (and Russian-allied) operators and has seen combat action against Chechen forces - particularly against enemy snipers in the "counter-sniper" role.©MilitaryFactory.com
