It is no longer usable. Kabam semi-fixed it: the parts can be clicked to a non-upgradeable state which throws errors on each attempt of upgrade. Equip and unequip such part if you want to break it to a repairable state. It is really messy what Kabam did with the turret parts. I'm waiting for next usable glitch in E-Lab :-)
