TFB writer and adventurer Claymore sent us this photo taken of him in the late 1970s …
This was taking during my try out for our SWAT team way back in early 1979. It was a Colt SP-1 very early AR-15 as you can see from the open prong flash hider.
If you look closely you can see the sling had a worn out slipping keeper so adapt, improvise, and overcome became the motto of the day and the result is the sling excess knotted around so the sling doesn’t slip.
Obviously I passed.
After training guerrillas in the mountains and jungles, I am sure a broken sling is nothing. Read about Claymore’s adventures here.
