For those who are wondering about the RA-tech NPAS installation, it's a straight drop in for the M4/416 open bolt nozzles (get the open bolt NPAS units...they're the ones that cost only $15). No mods required. I can adjust my fps from around 300 to 480 on 0.2. It seems the "mod" as described by RA-tech modifies this range perhaps increasing the maximum fps to a bit beyond 500.

Also when adjusting the NPAS unit, you'll need something to hold the unit in place inside the nozzle while using the NPAS adjustment tool.
