A little history first. Scratched the inner wall where the valve holder sits. Had to sand out the scratches but now the stock orings around the valve holder dont seal. I now sand my own orings to fit. And it works, holds air. Was shooting 18.13 g at 890. Degassed the dreamline to lower reg pressure. After filling ,it was leaking at the plenum. Removed the plenum to install new orings. Noticed a piece of oring coming out of the vent hole above the valve holder on the main body. After cleaning and installing new orings and filling with air, no leaks. Now shooting 770 f/s. Could this be a result of the vent hole being completly plugged now from an overly tight oring sliding passed the hole during the valve holder install. Any ideas would be great. Hoping to avoid removing air, last time it would not hold air again and new orings take me about 5 hours to sand down to work. Thanks guys
