Yesterday I got back out on the state land with my Xisico Sentry 705-9K .22. The previous evening I had torn it back apart because it had developed a leak (first one), when I got it completely disassembled I found out where it was leaking and it appears that it was leaking around the degas block in the air tube. Anyway I burnished the valve seat while I had it apart for good measure and thoroughly cleaned the degas block in hot soapy water and sprayed it out the best I could without removing the seat, it had debris on both o rings and a nasty gritty stuff all over it, where it came from must have been inside of it because it was clean when I assembled it last time. I also cleaned the air tube out thoroughly as well. All the o rings looked good so I greased them up with divers grease, reassembled, filled to 1.2Kpsi let it sit several hours then reassembled early yesterday morning. I had it already before daybreak yesterday and headed for the woods. I did two shots right when I got there to see where it was hitting and only had to tweek it to the left 3 clicks.
