wearing a rifle is still encumbering, in the same sense that they’re pretty big, and wearing 10+lbs around your neck on a 2point strap still would get in the way of various things especially without the training to deal with it. For that reason, along with the clothing/storage revamp that was being discussed in IRC, the best course of action may be to simply wait.
Right now, wearing a million tiny pouches will let me somehow carry an SKS in one piece, despite the thing being clearly longer than the pouches its being stored in.
