Someone on here maybe a year ago or so posted up a solution to the cut shuttle orings. They basically did a hand sanding and polish of all the sharp edges(edges only) around the shuttle valve. Something like that. I know that's what I would do if I owned one. They're such small orings transitioning over so many edges that bad things are bound to happen.
DM7 eye covers wanted. Black or silver dust.
