I decided to do some testing with my WE SCAR this evening since the Leafs game is boring...they're actually winning!

I finally installed my RA-Tech NPAS with the LAT piston head (installed on stock nozzle guide rod).
Shots were very consistent, and within +/-4 FPS of each other.
The RA-Tech NPAS dialed in nicely but it's a little hard to adjust with the tool and it requires you to hold back the valve disc with a small flathead screwdriver.

I also tried the LAT SS mag valve and it did increase velocity by +15-20 FPS.
Where it failed was when it was tested on full auto, it dumped a lot a gas and the ROF actually seemed to slow down compared to the stock valve.
This may be a part that someone might consider using if building a sniper platform, so long as it's used in semi-auto only!
