The SR-3 Vikhr (СР-3 Вихрь, Russian for "whirlwind") is a Russian compact fully automatic assault rifle chambered in 9×39mm subsonic cartridge. It was developed by A. D. Borisov, V. N. Levchenko and A. Tyshlykov at (Central Institute for Precision Machine Building) in the early 1990s and was manufactured in 1994. It is based on the AS Val silenced assault rifle but lacks an integral suppressor, and has a newly designed folding stock and charging handle for ease of concealed carry. The abbreviation "SR" stands for spetsialnaya razrabotka — special development.

After the adoption of SR-3, the FSB established new operational requirements with a goal to combine the qualities of the SR-3, AS Val and VSS Vintorez, resulting in a new variant designated SR-3M (СР-3М). It features a quick detachable suppressor and a redesigned handguard with a collapsible foregrip. The iron sights have also been relocated to the upper front handguard as opposed to being located on the suppressor, apparently for when the gun is used without the suppressor attached. For this weapon a larger 30-round magazine was developed, which can be used also by the AS Val and the VSS Vintorez.

The SR-3 compact assault rifle is chambered in 9×39mm subsonic cartridge. It primarily uses the SP-6 armor piercing ammunition with a hardened steel penetrator, that can penetrate a 6 mm steel plate at a range of 200 m. It also uses the SP-5 ball ammunition with a heavy bullet and PAB-9 ammunition, which is a lower cost version of the SP-6.

The SR-3 is based on the AS Val, but lacks the integral suppressor and has no capabilities on mounting one. As a result it is much more compact than AS Val.

The SR-3 features the receiver which is machined from a bar of steel, the gas-operated action with a long stroke piston, and the same rotating bolt group from the AS Val. It has a more compact, top-folding buttstock and a simplified flip-up rear sight which can be set for 100 meters or 200 meters distance compared to the AS Val. The redesigned charging handle, made in the form of dual sliders above the forearm, must be grasped by thumb and index finger and then retracted to load the weapon. The trigger unit is generally the same as in the AS, but the AK-type safety is replaced by ambidextrous lever above the pistol grip. The fire mode selector is of cross-bolt, push button type and located behind the trigger, inside the trigger guard.
