Rifle barrels

[truck driver]

How are under lever barrels attached to the receiver? are they screwed into the front tube block or pressed in?

Sorry, I don't know.... Different manufacturers may do it one way or the other....

HW 77-97 are press in & non serviceable.
AA TX200 family are slip fit with a retention nut & serviceable.
Walther LGU pretty sure are also a press fit ... tho don't quote me having been a spell sense handling one.

Thanks for the info. I was hoping they would be threaded and screwed so they would be easy to replace.
