Yep. MDT's works well. You can / should also consider Area419's rail if you plan to use their arca clamp for your bipod or their stops, etc.

The advantage is if you get their rail, it's scalloped, and works with their ARCA clamp which takes advantage of the scallops holding things secure. It will also allow you to use any other arca clamp that doesn't have the scalloped edges. (Henderson Precision, RRS, Gray Ops, SAP, etc.) Finally, even if you do use the MDT ARCA rail, Area 419's clamp will work, you just remove the pins from it that interlock in the scallops.
And yes, the MDT weights will work on it of course, as well other m-lok weight kits. The ACC allows you to use an internet weight under the barrel in the forend, but not critical, depending on the balance of your rifle and what you like. There are a few others who make m-lok weights, (gray ops, maz precision, snyder precision, etc.) and as incredible as it seems, you will never come to terms with the price you pay for 2 pounds of milled steel for your rifle.
I don't recall looking at the specs, but any idea on the weight of the southfork?
