The SV-18 is a Russian bolt-action bullpup anti-materiel rifle designed in 2019 by Kalashnikov Concern.
A single-shot breechloading prototype of the SV-18 was first unveiled at ARMY-2017, an annual Russian military trade exhibition. At the next year's ARMY exhibition, the first instance of a magazine-fed, bolt-action design was seen, and the weapon was finalised in 2019.[1]
One of the SV-18's requirements was that it weighed less than 10 kilograms, which led to it being designed as a bolt action, as the recoil created would have otherwise caused discomfort. A large muzzle brake is in place to reduce recoil.[2]
The SV-18 contains a rail on top of the receiver, and M-LOK slots on the handguard, for the attachment of accessories.[3]
