E mag "" chuffing""

[Slapshot Vrref]

So I just got my e mag yesterday , and put air to it this morning, it will fire a few shots fine , but then it " chuffs" ...
I do know that mags take higher imput pressure (800+psi) ... im not exactly sure what the reg that i put on it outputs .
What else could cause this ?? Do I need to rebuild o rings in the valve , level 10 ??

Before you do anything check the tank output pressure.
Then check to make sure it has a rt on/off not a ult.
Then i would check the level 10.

Do what superman suggests first and then before anything else, Chrono it. Adjustments to mags must be done at velocity. Kind of sounds like too many shims in the lvl10 assuming it has one

It could also be something as simple as your thumb screw being screwed in too tight.
