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 Vintorez and Val with the main discrepancy being the fixed wooden buttstock on the Vintorez and tubular metal buttstock which folds to the left on the Val. The Val is functional 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 (Val only), and magazines are made of a synthetic polymer. Both rifles can be disassembled to fit into a special compact case for transportation. Variants and derivatives The SR-3 "Whirlwind" (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 modernization 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 modernization 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. VSSM and ASM (6P29M/6P30M) are modernizations where the VSSM is equipped with an aluminum buttstock with an adjustable cheek and butt pad and a new 30-round magazine was introduced to be intended for use with the ASM. Both rifles are also outfitted with a Picatinny rail on the top of the dust cover and on the sides and bottom of the suppressor, forward of the handguard. The mounts which shroud the suppressor can be removed. Deliveries began in 2018.
