with no on off the pressure will make it hard to unscrew. if the gun fires, as you turn it out take a couple of shots and see if it degasses. At a certain point the tank will still seal on the asa but the pin is no pressed. if u take a few shots then, it wont be pressurized anymore and will be easy to turn. if it does not shoot, turn it out slowly so that when you do back it out far enough for air to escape out the asa it does not push the tank off the threads. but rather just lets the air out. basically, dont unscrew it fast an you will be fine, if u unscrew it real slow and start hear hissiing stop and let it sit. it may save your tank o ring since they can get ripped when degassing too quickly
