ULE Trigger Pull Question

[Toto]

i am going to pass from Co2 to HPA and i want to know if the ULETP will work on a Classic68 Valve

I cant remember if the ULETP dosnt work with HPA or Co2 or even if the ULETP will fit into the valve

I want to use the ULETP because since i install the LVL10 the trigger is realy hard to push than without the LVL10

thanks
Toto

take out your on/off, if there is 2 orings inside the valve, one inside the other, you can use the ult. if there is only 1 oring, then you can have the valve milled so that the ult will fit
