Another Impy Question

[KamakaziManiac]

i was looking at the review for the impluse and noticed that it could run on CO2 just like HPA. now ive heard people at my local field talking that it works better with CO2 then it does with HPA maybe there wrong but i just wanted to ask because im thinking of getting one but really dont know what to run the impy off of.

Any gun will run better off of HPA. If you've got the money, get HPA. If not, it will work just fine off of Co2 as long as you have it anti-siphoned (and I think you have to have an on/off valve?). If you've got the choice go HPA. It won't freeze up on ya and is MUCH more stable than Co2.
