...still be upgraded or repaired by? be repaired by proffesionals at a store or will they reject it for being modified illegally.....for example at a store like Evike
They still could. But whether they would is another story. It is NOT illegal to own an airsoft gun w/o an orange tip. It IS illegal to import or sell it w/o one. It's mostly for transportation purposes. You could call them to confirm if they will or will not do work on your modified gun.
