Since 2015, Silverback has developed high-performance spring-powered bolt-action airsoft rifles. The SRS platform set new standards in consistency and mechanical efficiency, later followed by the TAC-41 in 2021.
With the VKS, Silverback returns to its bullpup roots. The rifle shares core mechanical components with the SRS platform, including the cylinder, piston, and spring guide, while retaining the same 41 cc air volume. It also integrates the TDC hop-up system and a 63-round double-stack magazine.
This shared architecture provides immediate access to a wide range of existing Silverback upgrades and spare parts. Development focused on realistic, tool-less disassembly for easy maintenance, resulting in a quiet and efficient spring-powered bullpup platform.
The VKS draws inspiration from the real-steel Russian VKS (VSSK / Vykhlop), a bullpup straight-pull suppressed sniper rifle developed for special operations. While faithful in overall layout, materials, and design philosophy, this airsoft version includes adjustments necessary for airsoft use and is not a strict one-to-one replica.
The VKS is equipped with a long CNC picatinny rail, and no iron sights, like on the most recent VKS models. The use of a scope on a Picatinny mount is therefore mandatory. The rifle is supplied with two side Picatinny rails made from fiberglass reinforced Nylon. These rails can be removed for users who prefer a cleaner and more streamlined appearance, or can be used to mount accessories to the rifle.
Adjustable and modular hop-up system The VKS hop-up system uses the SRS form factor with the TDC adjustment philosophy introduced on the TAC-41 platform. The hop-up chamber keeps the same diameter and length as the SRS hop-up system, while introducing a top-down adjustment system for improved consistency.
The VKS hop-up chamber is currently compatible only with the dedicated VKS outer barrel.
The VKS is supplied with three different hop-up nubs:
Low nub (+0 µm) – factory installed.
Medium nub (+250 µm).
High nub (+500 µm).
A taller nub allows additional hop-up effect when required by your setup. Conversely, if your configuration experiences feeding resistance or BB jams, switching to a lower nub can improve reliability.
SRS outer barrels can be installed on the VKS when equipped with a FAST hop-up chamber. When using a FAST hop-up system, the VKS is supplied with a dedicated cover replacing the external hop-up adjustment wheel, providing a more realistic appearance.
The VKS was designed with a strong focus on realism and quality, both visually and mechanically.
The rifle combines:
Fiberglass reinforced Nylon polymer components.
Stamped steel top cover.
CNC machined aluminium internal receiver.
Steel components receive a hot black oxide treatment for protection. However, like real firearms, steel components require proper care. Regular cleaning and lubrication are recommended to prevent corrosion.
Each VKS receives an individual incremental serial number, engraved on the receiver and visible inside the magazine well.
