Looks like maliwan barrel but no, it does not exits
That was for Borderlands 1 though, And if Gearbox will integrate that into Borderlands 2 is completely up to them. :/
I'm truly sorry I also personally love the Bullpup Skin I think most of them were SMG's if I remember. I hope the new DLC will come out with some better looking weapons.
This is from the game's guide. Correct?
The closest you are gonna get to this design is Veruc:
If you notice them carefully, the only main difference between those two (apart from the coloring of course) is that the grip with the scandal has changed places with the ammunition clip. The original design's scandal's position seems like awkward where it is. In real life (LOL) you wouldn't be able to aim with that thing. Veruk's is much better
