AS Val and VSS Vintorez

The AS Val and VSS Vintorez are integrally suppressed and chambered for the 9×39mm subsonic cartridge. Four rows of nine holes are drilled in the barrel which follow the rifling and allows gas to escape the barrel behind the projectile into the expansion chamber which surrounds the barrel and extends ~20 cm forward of the end of the barrel where three baffles are located. The baffles are stamped out of a single sheet ~1 mm thickness and welded to a removable frame which is pressed against the front of the suppressor housing by a spring placed between the baffle assembly and the end of the barrel. The suppressor effectively reduces muzzle flash and muzzle report of the firearm to 130 dB. There are no design features which reduce the noise of the action.

Manipulation is similar to many AK-type rifles: charging handle on the right side, tangent rear sight, magazine release button behind the magazine well, and safety lever above the trigger guard. The fire selector is, however, located behind the trigger within the trigger guard. The rifle also has an "AK-type" Warsaw Pact rail for various optical sights, namely the PSO-1-1, PSO-1M2-1, and 1-PN-51 calibrated for use with the 9x39mm cartridge. The standard open sights are graduated from 100 to 425 m in 25 m increments.

The action is also similar to that of AK-type rifles with a similar long-stroke gas system with the piston located above the barrel. However, the design characteristically uses a rotating bolt with six locking lugs and a milled steel receiver. The AS and VSS share the same standard 10 or 20-round double-stack detachable box magazines and are compatible with the 30-round magazine of the SR-3M. Many of the components are shared between the AS and VSS with the main discrepancy being the fixed wooden buttstock on the VSS and tubular metal buttstock which folds to the left on the AS. The AS can be fired with the stock folded but the mounting of an optic will not allow the buttstock to close completely (like many other rifles with similar mounting solutions for optics). The handguard, pistol grip, and magazines are made of a synthetic polymer.

Both the AS Val and VSS Vintorez can be disassembled to fit into a special compact case for transportation.

The SR-3 Vikhr (Russian: СР-3 «Вихрь», romanized: Spetsialnaya Razrabotka "Vikhr", lit. 'Special Development') was designed for improved concealability by replacing the stock and omitting the integral suppressor and charging handle. The design process began in 1989, manufacturing began in 1994, and the rifle was adopted in 1996.

• The SR-3M is a modernised variant of the SR-3 that replaces the original SR-3 stock with one similar to the AS Val and introduced a new 30-round backwards compatible magazine. The handguard was also redesigned to include the rear sight and a folding foregrip.
• The SR-3MP is a further modernisation of the SR-3M which allows for the folding stock to be mounted at the base of the pistol grip for users wearing helmets with face shields or head-mounted night vision devices. The handguard was also redesigned to include two picatinny rails on the sides.

The 9A-91 and VSK-94 (Russian: ВСК-94 Войсковой Снайперский Комплекс, romanized: Voyskovoy Snayperskiy Kompleks, lit. 'Military Sniper Complex') are cost-reducing redesigns of the two rifles by the KBP Instrument Design Bureau completed in 1992 which also omit the integrated suppressor. Manufacturing began in 1994.
