Just had the same thing happen to my gen 1 R10. Replaced all the o-rings I could find, still leaked air. Replaced the regulator with a huma version. Airtight for 3 weeks so for. note: remove the pressure sticker and make marking before you do. The sticker sometimes comes loos….
How are you users experiencing the SE version? Better than the mk2? Any issues like chrome of the bolt that comes lose, regulators that fail. thanks for the feedback.
