RA-TECH Magnetic Locking NPAS Aluminum Loading Nozzle Set
(Model: WE MSK GBB)

"This product is a significant improvement over the old NPAS system. I used to dread having to adjust my NPAS: The tools were small, I'd have to jigger the system to pinch the valve just right so the adjustment tool could actually do it's job, and I'd almost always rotate the valve incorrectly. The older system over time would also "slip" causing my FPS to drift in either direction over time. It was time consuming, frustrating, and unfortunately - necessary at the start of every single event.

All of these pain points have been resolved. The new magnetic locking mechanism and stepped adjustment built into the unit makes adjusting your FPS astronomically easier. The system comes with 3 colored valves with varying size of nozzle so that you can simply pop in the corresponding color based on your need. Blue = Low, Green = Standard, Red = High. Once a nozzle is installed you can additionally open/close the flow valve to further tweak your gas flow. Swapping nozzles is as easy and natural as unscrewing a battery compartment on your TV remote. It is also now impossible to adjust the NPAS to unsafe levels, and the magnetic locking system ensures that the adjustments you set it to are NOT going to drift with recoil overtime.

I cannot recommend this product more. Ditch your old NPAS, this one is here to stay.
