6000psi tank is what you need to fill the 4500psi tanks. You can fill from there if you have it regulated. but I would just fill the tanks.
Well guys thanks for all the great advise. The advise i took was the guy that said, if there was an air tank and a marauder on a table and they were both free. Which one would u pick if u could only pick one. Well i chose the marauder. Thqnks guys i just ordered the new woodrod in .25 cal from PA. I bought the bundle and used the 4th of july code. I am so excited!!!
