If you own a Tokyo Marui MWS, or one of the popular clones like GM, Unicorn, or BJ TAC , and you want a reliable way to tune your FPS, this is the valve we recommend to pretty much everyone who asks.
The Federal Concepts FEDA Adjustable Valve is our top pick for the TM MWS system because it just works. It handles temperature changes well, which matters a lot if you play in varying conditions, and adjusting power is straightforward once it's in. No fiddling around, no surprises.
Installation is identical to any standard TM part, so if you've swapped internals before, you'll have this done in minutes.
Compatible with: Tokyo Marui MWS and clones using GM, Unicorn, or BJ TAC nozzles
In the box: 1× Federal Concepts FEDA Adjustable Valve (NPAS)
