Good afternoon all, I've settled on a BFG VCAS sling however I'm baffled at how many different attachment points there are available on the market. After doing some research I plan on running it through the factory location at the rear of the stock and then picking up a PMM QD for the front. I don't want to add too much weight (I know it's only a few ounces) with all sorts of metal QD mounts and what not but I'm curious why so many people mount their slings where the factory HK style attachment points are where the stock folds but add a QD there. The only reason I can figure is if you wanted to run a single point and that was your main attachment point but then you loose out on having the ability to have the weapon tight to your body for transitions or slung over your back. I know everyone has there different styles and different preferences, I'm just curious how you guys run your slings but more importantly the reasoning behind it. Thanks
