Air Arms Owners Club

Hello members and seasons greetings to you all.
This is probably an easy to answer question, so forgive my stupidity
What brand of barrels were used on the EV2MK4? Thanks in advance for any answers

Merry Christmas to you too.
Not 100% sure so I would pm Julian Bond to confirm

BBF

What are the possibilities?
Lothar Walther or CZ?
Have they used any others?
