Silverback - VKS long version spring
With the VKS, Silverback reconnects with its « bullpup » origins. It combines modern and compact ergonomics with proven mechanical solutions from the SRS and TAC-41 platforms — notably the same cylinder, piston, spring guide and air volume of 41 cm³ — while integrating a TDC hop-up system, a double-column magazine with a capacity of 63 BBs and a design allowing tool-free maintenance.
- High-end replica of the Russian VKS (Vykhlop / special purpose silenced rifle)
- Bullpup design offering a long inner barrel while maintaining a controlled overall length
- Spring system with linear reloading bolt
- Magazine of 68 BBs of 6 mm, with 5 additional BBs in the feed tube
- Particular reloading with magazine insertion from the rear
- Optimised for heavy BBs from 0.40 to 0.48 g
External construction:
- Stamped steel housing
- External elements in reinforced nylon polymer
- Specific silencer in fiberglass (model « Exhaust »)
Internal features:
- Main components reinforced with steel: firing mechanism, trigger and sear
- Inner barrel and seal compatible with AEG standards
- QD quick change spring plate
- APS standard piston spring
- TDC hop-up system
- Two-part locking mechanism
- Compatibility with the large volume cylinder architecture of the SRS and TAC-41
Main common components with the SRS platform:
- SRS compatible cylinder
- SRS compatible piston
- SRS compatible spring guide
- 13 mm APS springs compatible with SRS
Cylinder specifications:
- Bore: 23.8 mm
- Stroke: 92 mm
- Usable air volume: 41 cm³
This compatibility allows immediate access to the entire range of existing upgrade and replacement parts for the Silverback SRS:
- SRS VMP piston
- Advance piston head
- Aluminium/PTFE spring guide
The VKS is equipped with a silent piston head with air brake. The longest air brake is installed as standard.
The choice of air brake can be optimised based on:
- The length of the inner barrel
- The weight of the BBs
- The desired performance
