I had an air leak on my Reximex Mito. Started off a slow leak taking two days to loose pressure. But then it went to overnight. Found your excellent video and proceeded to check. When I removed the regulator and checked, the valve didn’t pop out it was flush. I noticed a thin slice of rubber sticking out jamming it in place. I put the regulator back on but spaced it out with washers either side. Screwed the air cylinder back on, cocked and dry fired and the valve was pushed out. Changed the damaged O ring, reassembled. No further leak. Thanks for posting your video. 👍🏻

I was lucky mine didn't leak on delivery. BUT I know it will eventually so thank you for making this video how to address this for everyone! 😊

Gd job ty man😊

Brilliant video!
Mine had a very slow leak (3+weeks to empty) on the hammer valve.

I think my brand new one has the same issue, I can't fill it and air leaks in the barrel when I try to fill it. I will send it back and ask for a refund, I'm done with Reximex. Thanks for the video.
