In the picture, I have 2 slings. One is MY original sling that I was issued with my M40A1 at Horno (Some how I letft Horno with it) and the other I bought several years later. The original (86) only has 1 leater band, and the newer one has 2 leather bands. Does anyone know if my original one had 2 keepers at one time and I lost one, or did they change the slings to include 2 keepers later?
