FX M3 refill question

[Flyer1944]

I have a question about the FX M3 rifle when it comes to the two regulators no refilling the Gun.I have a Dreamliner which I refill just before the pressure reaches the set pressure .My question is with the two regulators do you refill when the 2nd reg hits lts set point or the 1st reg.I want to say the second reg any thoughts?

You can wait until it's just above the set point on the second reg but I refill when it's at or around that point on the first. I get a boat load of shots per fill and have a compressor so it's easy.

agreed,
you can wait till just above the second reg set point.

myself i usually refill when i notice the first reg dropping below its set point,
but thats just me lol

The first Reg is there to do the High Pressure Regulation....
This reduces the Stress on the 2nd Reg. Allowing the Second Reg to do a better job of regulating the Pressure!
So Refill when the Pressure is close to or below the 2ND Regulator's Set Pressure!!

If you wait until it's below second reg you won't get consistent shot velocity.

If you are BR/ Target shooting.... The accuracy may drop slightly...
In the real World, out hunting and a target presents itself..
My tank isn't close by for a refill....
The Bottle Pressure happens to at or below the actual SET Pressure of the 2nd Reg...
I will still take the shot... compensate for velocity drop...
Rinse and Repeat as needed. until I can get to my tank for a for a 300 bar refill
