Leak down the Barrel

[venison]

Guys i'm sure you have answered this a thousand times but I gotta ask. I just recieved a RT valve for my 68 automag.I use a preset ACI compressed air tank. When I screw the tank on air leaks full pressure down the barrel.
I am not an expert on the RT Valve but i took it apart and checked the o rings made sure it was lubricated used the smallest spacer. and still when i put the tank on, air down the barrel. I changed back to the stock valve no problem. Can any one help

put straight shot down barrel, hold bolt back while turning the air on. common problem. I had that problem with the old RT had a maxflow on it. Was told max flows turn on to slolwly to try and get a flatline system cause they turn on much faster and fixed the problem for me.

Power tube spacer?

It could be your power tube spacer...I think it is
Bolt Stick=Shorter
Barrel Leak=Longer

I'm not sure, I'm new to mags, you should check.

get a slide check or get a proconnect. rt's need that instant surge of air to push the on/off pin and if that does not happen air leak out of the barrel.and check your powertube spacer that would help.

Just hold the trigger down as you gas it up. A much simpler solution.
