This is another item that depends on how you use the rifle. I have one of these on my coyote killer, but it does have QD swivel mounts so I can take it off. However, on my SHTF Sport II, I have this sling because the single point configuration allows for quicker "grab and shoot" action than when it is in the two point mounting configuration. It does require you to change the back plate on the lower in order to use the single point swivel.
