NPAS V3 Adjustable Nozzle Set for M4 - HK416 GBBR VFC

This NPAS V3 adjustable nozzle kit for VFC/Umarex M4 and HK416 GBBR replicas is designed for replacement or upgrade on these platforms. Its main advantage lies in the integration of the NPAS (Negative Pressure Adjustable System), which allows you to adjust the firing power via the nozzle's internal valve, without complex disassembly or valve spring replacement.

Made of reinforced polymer to withstand the repeated stresses of the blowback cycle, this nozzle ensures a constant seal and consistent feeding of BBs into the hop-up chamber. Its 20 g weight preserves the bolt carrier's responsiveness. Whether replacing a worn part or adapting the replica to a field's power limits, this VFC part guarantees perfect mechanical compatibility with M4 GBBR and HK416 GBBR replicas.
