"Gun used was a KWA M93r, internally is almost identical to the MP7.

Stock rocket valve: 360-390FPS

Aftermarket CQB valve: 320-350

NPAS: Maximum FPS: 260 Minimum FPS is 150 FPS.

As you can see that FPS range is kind of pointless, but very consistant. On a single mag, from start to finish the FPS only ranges by 10 FPS at most which is really good. The other valves had a range difference of 30 FPS from start to finish. I just wish the NPAS had a more useful stock adjustment range; but this can be compensated for with a shaving process; which is something I really don't want to do but I will if I have to.


Pros:

Easy to install
FPS is adjustable

Cons:

Really expensive, which sort of makes sense since this item has to be machined... but it is still very expensive.
FPS adjustment range is REALLY low...
FPS adjustment tool is also too short. I have to disassemble my slide to even use the tool; which isn't a big deal really. Just more things for me to pick at in the end.
