Evanix max barrel measurements for machining

[MarkAus80]

Hi people!
Im in need of a .22 barrel for my Evanix max auto project as it came to me as parts with no barrel. Does anyone know where I could get one from or even another brand that would suit? Have been searching the web for one for a couple of months now and found nothing. Was considering a blank and getting it machined but I cant even find any technical measurements for the o-ring grooves, transfer port etc either. Any info would be greatly appreciated!! 

Mark 😊
