Does anyone know if the shocktech (tremor) autococker cna run on Co2? If not, can any1 recommend a cheap N2 system- I dont need angel air or some pro $h!t like that. Currently im going to get the shocktech tremor, luckily no barrel or reg come with it, in silver from paintballgear.com, add an orracle regulator, clear egg II loader and a freak barrel. What do u think? Do i need a compressed air system, considering I live in thailand, so i dont really get spikes- in fact having a cold tank has its benefits in weather of up to 40 degrees celcius. So, can it run on co2 or do i have to shell out for money on a N2 system? If so, any reccomendations?
