no rapid fire

[Thunder Bunny]

on an RT mag with L7 bolt. What would keep this from happening, besides not enough input pressure? I can rapid fire mine no problem, but my brother's won't. What should I look for?

Whats his setup tank wise and what is yours?

[Thunder Bunny]

We used my tank to try his gun. A 68/45 nitro duck adjustable. Supposed to go to 900 psi. We had the pressure cranked all the way up and 4000 psi in the tank.
Maybe I can respring the reg to get more pressure?

mabey he have a ule on off, that would take away the reactivity

I don't think he has ULT. I didn't see any shims in there when I took it out. I swapped on/offs with him and nothing.
