If you use that Front Sight Base [FSB] QD point, be aware of how it's placed and how you plan to use a sling. Looking at it, it appears to be on the bottom of the FSB. SO, every time you use that attachment point, the sling will attempt to rotate so that that attachment point is toward your body. That means the rifle will be trying to turn the bottom side up all the time. Compare that to a side mount QD attachment point, that will keep the respective attaching side toward your body. For me, having the side of the rifle facing my body allows easier carry and recovery of the rifle to a shooting position from a slung position, especially with a magazine hanging out of the bottom.
