The Mk. V Ripper Gun is a bit of a sleeper pick right now, having excellent Monstrosity and mixed-horde killing power. If you space out your shots, you can even kill specials from surprisingly far away in just a burst or two. Add in the phenomenal all-around performance of the Mk. XIX Shovel and you have a build that can handle anything Aurics can throw at it.
The only change I'd consider making would be dropping maybe "Good Shootin" or something in exchange for "Pacemaker", but I don't really magdump my Ripper Gun into hordes all that much, and even when I do I'm likely using it with Point Blank Barrage active so I ultimately decided against it.
