I can't get my 3 point or my single point sling to feel right (it folds up along the left side of my face and feels uncomfortable) when I shoulder up since the sling attatchment is facing up at an angle on the upper side of the base of the A3.... the 3 point works great with the A2 stock....  what do you guys use and how for the A3 configuration?  

Bothers me so much, I might just switch back to the A2, but the A3 is great for "traveling"

for BW5-SBR and Vector V53 SBR

I put on a troy industries single point sling
Much better than the standard H&K for use as a tact sling.
