Gentlemen and ladies (if on hand), I ask for your assistance troubleshooting a friend and fellow member's mag. Sorry it is long winded, but I am trying to give as much info as possible.
Specs - classic valve, ANS back and adjuster, ANS on/off valve, level 10, ULE body, intelliframe, RT-Pro (I think) rail.
Story - He had a very minor down-barrel leak and asked for help tuning the level 10 kit to eliminate it. He also wanted me to polish the parts up since they were rather dull. He acquired the marker sanded and poorly polished. We gave it a good cleaning and ran it across the buffer. Looks much better. On to the level 10 tuning following the instructions from the beginning... Several hours later and countless combinations, it leaks like crazy and in an odd manner. Oh by the way... Before we started the carrier it had in it, I believe the single line one, did not have the Oring on the outside It also did not have any shims in it.
Video of leak since I can't explain what it is doing...
Troubleshooting after the video was taken - I have a level 10 smart mag the is fully functional and leak free so I swapped parts until I narrowed it down. Reg back, on/off assembly, full level 10 kit.
With my level 10 kit (all pieces, including bolt, spring, and pt tip) resulted in a properly tuned and leak free marker. I then proceeded to swap out all pieces one by one. With his original Orings and the smallest carrier, no shims and my bolt I got it to stop leaking for about 10 shots. Then it started leaking down-barrel quite a bit. It changed when I pushed in on the bolt with a dowel rod but did not go away. If I swapped the bolt and spring over to his pieces it leaked like crazy and would do what it did in the video. The 3 smallest carriers all with different outer Orings result in the same thing.
Thoughts? Just get new Orings and start over again? Could the bolt be an issue? He bought the level 10 kit used and separately from the gun.
Thanks for the help,
Tony
