My NPAS installation was successful. I can now get a low of 275 to a high of 425 fps on .20.

I had to mod the rear part of the nozzle by removing around 2.5mm off the raised tabs (pretty much cut them off but left about 0.5 mm on both sides). Also cut the rest of the base the same 2.5mm so that I maintain the same sized openings so that gas can flow to the carrier.

I think if you just went ahead and cut off the tabs entirely (and also remove at least 2.5mm off the base to maintain gas flow to the rear) you'll get closer to a max of 450 fps and a low of 300 or so.

I did this all with an exacto/box cutter knife. Pretty simple 5 min mod. Don't mod the spring.

Ready for battle!
