RA-Tech Magnetic Locking NPAS Type 3 Loading Nozzle Set - TM M4 MWS / MTR-16

The RA-Tech Magnetic Locking NPAS Type 3 Loading Nozzle Set is a drop-in upgrade designed for Tokyo Marui M4 MWS and MTR-16 GBB rifles. It allows precise adjustment of muzzle velocity (FPS), making it easier to adapt the replica to different field limits and weather conditions without additional modifications.

The nozzle is constructed from durable composite materials and features a steel nozzle head for improved longevity. The integrated NPAS system combined with RA-Tech’s patented magnetic locking mechanism keeps the adjustment securely in place during use.

The Type 3 version includes a universal adjustment tool, allowing NPAS tuning without disassembling the replica or removing the bolt carrier group. This makes on-the-go adjustments quick and practical.

The design also improves gas efficiency, feeding consistency, and overall reliability, including better performance in lower temperatures.
