RHD VFC Nozzle with Flux Core (C-Lock)
Description
Description
Improve the gas seal and feeding of your VFC M4 or HK416 gas blowback rifle with the RHD Flux Core loading nozzle. It is a complete polymer nozzle assembly, with RHD's Flux Core return spring and an adjustable flow valve (NPAS, or Negative Pressure Adjustment System) already fitted, so it simply replaces your rifle's original nozzle.
A tighter gas seal
The Flux Core spring works in both directions, pushing and pulling. Once fitted, it holds the nozzle slightly forward, keeping it pressed against the bucking right up until the shot. That minimises gas leaking past the BB, so more of each shot's gas goes into firing it.
Reliable feeding, stable cycling
In the last part of the bolt carrier's forward travel, the spring helps the nozzle push the BB firmly into the chamber, for more reliable feeding and more stable cycling. RHD spent two years field-testing and gathering data on the Flux Core design before release.
The Flux Core nozzle is for VFC GBBR owners who want more consistent performance from their rifle, as a drop-in replacement for the stock nozzle. Browse our gas blowback rifle parts, VFC range and the rest of the RHD range.

Frequently Asked Questions
Will the RHD Flux Core C-Lock nozzle fit my VFC GBBR?
Will the RHD Flux Core C-Lock nozzle fit my VFC GBBR?
It fits VFC M4 and HK416 GBB rifles that hold the nozzle spring with a C-clip, including the MK18, URGI, M733, HK416D, HK416A5 and M27 IAR. It does not fit the VFC "EVO" AR system. For the VFC LAR, APFG MCX or Maruyama ISO556, choose the Flux Core Bolt-Lock nozzle instead. If you are unsure, contact us before ordering.
Is the RHD Flux Core nozzle easy to fit?
Is the RHD Flux Core nozzle easy to fit?
It replaces your original nozzle directly, but fitting needs some DIY confidence, as the bolt carrier has to be stripped. Reuse the C-clip from your original nozzle, and apply a thin layer of airsoft silicone oil to the spring and nozzle O-ring. As the nozzle affects your FPS, chrono the rifle after fitting and set it comfortably within your site's limit. If you are new to GBBR work, we recommend having it fitted by a tech.
What is NPAS?
What is NPAS?
NPAS stands for Negative Pressure Adjustment System. It is an adjustable flow valve in the nozzle that controls how much gas reaches the BB, letting you fine-tune your rifle's FPS. This nozzle comes with one already fitted.
