Reducing FPS without impacting performance?

Recommended Posts

Hi all, I've an VFC FNX 45 that's hooting a bit hot, even with a standard barrel. Is there a good way of reducing the FPS without severely impacting FPS consistency? I'd like to avoid drilling holes as much as possible. I know you get discs that restrict gasflow for GBBR nozzles, would those work?

Thanks.

Bit of a shameless plug here but I've got a VFC FNX sitting in my office, and I also make restrictor discs for that very purpose for the VFC MP7 and they do fit into the loading nozzle perfectly.

Obviously as I've only just tested the fit I don't know what kind of FPS reduction figures they'd give but it stands to reason they will reduce the fps without reducing recoil, I found consistancy was much the same as stock in the MP7 so I'd be suprised if the FNX is any different really.

Buy the floating valves that he makes. That's the easiest solution.

In general, if you're in a situation where you have to modify something, you want to modify the floating valve. What i've done sometimes is cut a groove in the wings on the floating valve, and then slip a tiny oring on it. This reduces the flow and you can adjust it by switching o-ring size.
