VFC Adjustable NPAS Nozzle Set, AK
An adjustable NPAS loading-nozzle set for compatible VFC AK-series gas blowback airsoft rifles, allowing the gas flow and muzzle velocity to be tuned for different field limits and playing conditions.
The VFC Adjustable NPAS Nozzle Set is designed for compatible VFC AK GBB airsoft rifles. It replaces the corresponding factory loading-nozzle assembly and adds an adjustable gas-flow system that allows the user to fine-tune the rifle’s power output.
By changing the NPAS setting, the amount of gas directed toward the BB can be adjusted. This makes it possible to reduce or increase the muzzle velocity within the adjustment range of the system, helping the rifle meet different field limits or suit changes in temperature, gas pressure and BB weight.
Adjustable gas flow
The NPAS system provides a practical way to tune the rifle without relying solely on changes in gas type or ambient temperature. Correct adjustment can help achieve a more suitable and consistent power level for the intended playing environment.
After every adjustment, the rifle must be tested with a chronograph using the BB weight and gas intended for play. Gas pressure and muzzle velocity can change significantly with temperature, so the setting should be checked again when conditions change.
Replacement loading-nozzle assembly
The set is intended as a replacement or tuning component for compatible VFC AK GBB systems. Installation requires disassembly of the bolt and nozzle assembly and should be carried out carefully to avoid damaging seals, springs or other small components.
Professional installation is recommended unless the user is familiar with servicing gas blowback rifles. Correct lubrication and alignment are important for reliable feeding, gas sealing and cycling.
