M3 Delete the Reg
This part deletes the first reg between the carbon fiber bottle and the main action on an M3.
If your M3 is for slugs, then you may find better performance with a higher pressure and flow behind your second reg.
Due to there not being a regulator through the center, you are now able to use any FX CF bottle on your Impact.
Make sure that you keep your bottle pressure under 250bar with the first regulator removed. The FX second reg isn't designed to take pressures above 250bar.
