Anybody who needs a barrel band mounted sling swivel doesn't know how to hold a rifle correctly,or has too short of a forend.
Or they are using one of 458Win's picatinny rail flashlight mounts - I've put these on a couple of my rifles and they are awesome. A sling hanging in front of a flashlight would probably block some light, but I suspect enough would "flow" around the sling much as it does the barrel itself - I'll have to try hanging a strap in front of the Surefire Scout tonight to see. Regardless, if the stock has a conventional sling swivel location, or at 45* on the tip as mine do, there's obviously no sling to get in the way. Of course if one removed the sling from one's barrel-band sling swivel/pic flashlight mounted rifle there wouldn't be an issue either....
