HELP i want to increase the RT reactivity!!!

[elephant toast]

hey, i want to increase the reactivity of my ULT trigger kit and i kno i have to increase the pressure, but how the hell do i do that? ok my set up is a tac one with a ult trigger pull kit and im using a crossfire 68/3000 with a max output of 800 psi help the noob what do i do???

if u want a reactive trigger install the stock r/t on/off. the ult greatly reduces the reactivity but give u a very light trigger.

You need an adjustable tank.

a standard HP output on a tank will make an RT on/off bounce with some adjustment, but your best bet is an imput of 1,000psi.

Can you shim a crossfire reg? I knew this last month...

Some of the fixed regs can be changed to get up to around 900 psi. That would help a lot. I've read where some guys use around six shims in a ULT with higher output fixed bottle reg for a reactive trigger.

But the easiest is the stock on/off with an adj. reg. It gives you a lot of control on the reactivity and rate of fire. Shimming the on/off only seems to be all or nothing. You need good flow on the reg too. Crossfires usually have that if not the pressure.

The old AGD 3k flatlines barely worked for a reactive trigger (i.e. add on/off shims too).

Actually, just start with Zak...

Adding shims to your ULT should help. Else use your stock on/off and you can try a slightly shorter pin (which is NOT factory recommended)

I have a 4500 flatline and I dont get much difference going from 800 psi to 1100
