I had replaced my screw o ring out of precaution on mine from suggestions on a post somewhere else but was a year ago. I had to remember how to do it but glad I came across your post here.Yes, these are the 2 known issues with the Notos. Both of them could be fixed for pennies at the factory. If I could find the barrel orings in 90 duro, I'd be king!
Yeah I can't believe they'd think it necessary to use such thin o rings for the barrel.. and then in 70 duro too. Would gladly pay $5 per Notos for them to make the o rings twice as wide in 90.
