Wife just got me one of these for our anniversary, it works great would highly recommend to anyone wanting a sling without having to modify you gun at all. Also it is compact enough to slip in the back of game bag never know it is there. Very nice for those times you have a long walk back to the truck. Might only use couple of times a year but quality of the leather pretty sure my son will never wear it out when I am no longer using it.
