Active interest in large-calibre sniper rifles was provoked by desire, on the one hand, to increase effective range of fire against five targets at a large range, including those wearing personal armour protection kits, and, on the other hand, to enable snipers to defeat pin-point enemy targets (such as hardened fire emplacements, small-size stationary weapon systems mobile missile systems, radars, satellite communication antennas, light armoured vehicles, transportation facilities. and so on). Powerful cartridges used en large-calibre machine guns formed the basis for the development of these rifles. Thus appeared a new type of firearm systems.

Designers E. V. Zhuravlev M. Yu. Kuchm, V. I. Negrulenko and Yu. N. Ovchinnjkov developed the 12.7 mm SVN-98 rifle (sniper rifle of Negrulenko mod. 1998) in the bullpup configuration. Subsequently the rifle was designated KSVK (Kbvrov large-calibre sniper rifle) and, later on re-designated ASVK (large-calibre army sniper rifle).

The ASVK rifle is a non-automatic magazine-fed large-calibre firearm. The rifle features a free-floating cantilever barrel manufactured by the radial cold hammer forging method, and mounted so that it contacts no other rifle components. The barrel is provided with an efficient active-reactive muzzle brake or a device combining functions of a muzzle brake and a flash trap. The barrel bore is Socked by a sliding longitudinally, rotating bolt with the reloading handle positioned to the right before the trigger guard. The heavy free-floating barrel, rigid receiver and manual reloading method contribute to improved accuracy of fire The opening for spent cases ejection is closed in the marching position by spring-loaded lid. The safety lever situated on the right serves also as a holder of the receiver opening lid.
