Well, nitro (nitrogen: N2), and HPA (high pressure air: compressed air) are not the same thing as I just showed you. But any HPA tank can be filled with either because they both have the same effect. There is no noticeable difference between the 2.
There is nothing required for you to do to your marker, or tank in order to switch from Co2 to HPA. Just buy the tank, fill it, and go play.
yes there is a big difference in the 2 you cant breathe pure nitrogen very long, when it is released in a small room. i had a bad experience while working on a HPA tank, i had to add that but yeah there isnt any performance differences.
ya N2 tanks are the same as HPA tanks so if you have HPA or N2 tanks thye will work with both...but never use a CO2 tank for HPA or N2...or vice-versa.
The simplest and cheapest way is to get a HPA tank with a preset regulator. Make sure it outputs close to 850 since that's what your gun is tuned to stock. If you are going to pay the premium for a HPA tank though you would probably be better off in the long run by spending a bit more for an adjustible one which will let you lower the operating pressure of the gun. With a different valve spring and main spring you can probably get the pressure down to around 500 and still keep your FPS close to 300 without any other modifications. (venturi removal, highflow valve/pin, drilled ASA)
