FX Crown, is this normal?

If you want you can remove the flow stricter screw, the gauge needle will move so fast with the pressure and stabilized .010 second. depending how many rounds you are shooting will determine the life of the gauge or failing accuracy of the gauge, will gauge are cheap easy to replace.

You just now eliminated hmmmm maybe 90% of the complaints and the all of them "for nothing" worriers. 3m stock suddenly plummets... BRAVO!!! Yo!
 
The impact flow restrictor is the valve housing—-> one of the leg is blocking the hole to the gauge so the flow has to go around the leg and go through the tight clearance between the rear black and valve housing, on my power mods and m14 external plenum i cut the leg off and drill and tap the rear block so far I only replace about 2-3 gauge in 6 impact of my own due to no flow restrictions.

Looks like 3m is still half safe for the IMPACTS then well maybe not...OR...wait for it... 😉 Yo!



Use THIS to cover the regulator gauge!
