@JahDropper npas allows you to change the fps on your gun to meet the limits of different enviorments. when playing indoors(which limits are gennerally lower) you can lower the fps so you can play. Outdoors, you can raise it for extra range and accuracy. it depends on your preferences and where and how much you play.

Can this valve and rod fit in a we gbb pdw bolt carrier? If so where can i order it?

My bolt/nozzle looks completely different. I don't get it, my agm m4 is destroyed because of npas installation and now my scar bolt looks totally different... I don't have the hole in the carrier. I do have the top hole but the bottom one isn't there...
Getting tired of this ra-tech stuff! No manuals or customer support whatsoever!
