help a new guy

Okay so I Have an A-5 with response trigger, and I just upgraded to a 72cu N2 tank regulated to 500PSI, i noticed that ever since I got the tank first filled I cannot seem to get my trigger dialed in. I contacted the tank manufaturer (Pure energy) and they are sending me a 300PSI reg for the tank, but I am not sure if this will fix my problem. Does anyone have any good insight on this? or am I going about the response trigger problem all wrong?

You should of gone the other way and got a higher output. Like a preset tank at 800 psi. Call Tippmann and ask for the Low Pressure Response Trigger Retro Fit. What that is, is larger diameter hoses that will flow more air into your Response trigger. Basically the RT kit doesn't like to work on low pressure so you have to get bigger hoses which will feed it more mass of air using the lower pressure (500 psi) that your tank is providing. Your C02 tank is providing around 600 psi by the way. 600 to 800 psi makes the Response trigger work fine. 200-500 psi and you will need the LP retrofit kit
