when i am shooting/carrying right-handed, i place the forward QD on the L side and the rear stock mount on the R. with the sling tightened down, the rear either goes over the butt or over the top of the stock. switch both for L handed operation. (i have learned to shoot L or R handed due to R shoulder injury i am still rehabbing. in reality it has been good to be forced to train on my non-dominant side, because, you never know ...).
