i recently changed the lens on my proto switch FS, and when i reassembled it the hard goggle wouldn't fit back onto the mask properly, it sticks up slightly at the edge. i tried diassembling it and reassembling it several times, but it still won't fit properly. it also started to make a creaking sound when i moved it. is there a problem with it? im not sure if it is still safe to use. would it be worth changing it for an Axis?
