ALSO, there's a typo in the picture description.
"One of the Borderlands2 weapon manufacturer is Dalh."
Dahl is spelt wrong. (Just saying...)
Wait, I just realised after a close look at this gun.
I can see the bullet chamber ends with that small hole at the top of the front end...
So what's that great big orifice at the front? Some huge-ass grenade launcher?
(Woulda loved grenade launchers in Borderlands 2...)
