Umarex Gauntlet .30 barrel?

Does anyone know what make the barrel is in the Gauntlet .30?

When Umarex sold me a hammer they had made a comment that "like our other pcp air rifles the hammer also uses an LW barrel" ... so im curious

Thanks in advance
Also the Hammer used a Walther barrel but it was a Carl Walther not Lothar Walther. That might have changed but that was the original barrel. They were father and son gun makers in Germany. Carl Walther "Walther" is the parent company of umarex. I do think they have a few rifles with LW barrels like the 2nd Gen Reign but most are not.

Thanks a bunch for that bit of info, I searched but couldn't come up with much. You the man!
