Guns Modify High Stability DIY FPS Nozzle Valve for Guns Modify MWS V3 Nozzles
(Package: 3 Pack)

"These are standard valves. They are in a pack so you can shim the inner part of the valve with tubing to have fixed FPS outputs. These are perfect for replacing the original TM valve but they perform the same so it’s not an upgrade part. These DO NOT fit in the Double Eagle Noveske nozzles without extensive modification. They do fit the original TM nozzle. These two nozzles are the only ones I’ve tried them in.

TL;DR:
If you’re looking for a pack of valves to do your own adjustment to or if you want to make some grub screw NPAS’, these are great if you have a TM nozzle. If you bought the Double Eagle Noveske, it won’t fit that nozzle without modifying them. But that’s because DE is slightly off TM-spec for the nozzle. To be clear, these are not an upgrade part. They perform exactly the same as the stock valve.

"These are just 3x of the same valves that comes with the GM 3.5 nozzle. You can either add material to the return spring side or drill and screw a grub screw in to adjust the fps but they are very very DIY. They will not alter your FPS out of the bag.
