I already have it on the rifle so measurement isn't exact but I'd say it is 46" from center of buckle to end of leather. Mounted you will lose 2" for the upper attachment and 2" for the buckle end so 42" net. I always tighten them as snug as they will go so they aren't flapping all around. I also got one of the Rhodesian rifle bags on a whim. Kind of neat, not sure they are original but they aren't expensive either. Soft padding on inside but won't take a lot of abuse. Fairly light construction.
