If you look closely, one of the 3 hardpoints in the right shoulder is not on the low waist level but on a high shoulder position, I would use that for a ppc.
Thanks for bringing me back to this post, this should have actually been a assymetric build. Updated the smurfy link. But yes, the torso is also an option, yet I like to use the arm for cornerpeeping and torsotwist sniping
