So if I understand you correctly, the 2027 Airtube is 21.78mm? I have yet to fire mine & it is still holding @ 2000 psi from the Pyramid Air 10 shots for $10 quality control service. I could degas it …
Picked this little guy up for $110, cleaned all the internals, added a oring behind the hammer to reduce bounce and lightened the hammer spring. Added a 18" barrel from a Barra 1100z. 40 is the furthest I can shoot at my place but I really want to see it at 50 and beyond. Getting 36 shoots 2800-1200 psi at around 750-800 fps.
