Disclaimer: May need minor work, was leaky before I replaced the face seal, but I don't have any CO2 to test it with.
Non-cartridge valve PG with Valve tool, just not enough use for it
I have a valve tool on the way which I can include for $10.
Face seal may need to be re-replaced
It's in darn good shape, and comes with new delrin ball stop from Titus. $55 shipped OBO (Flat rate w/insurance)
