can i use nitro on a completely stock tippmann?

can i just screw in a nitro tank with a stock tippy?

Yes you can. HPA systems are set at about 800psi output. So since the operating pressure is set for that 800psi due to CO2's unstabability, HPA is fine stock.

Be careful, don't get the 450psi preset. That won't work. Must be the 800-850 psi preset.
