No, its 2 rifle slings, 1st has one end looped back on its self through one Bren sling clip from the butt with the other end just looped back. The second sling has passed through the other clip on the bipod and both brass ends of the sling are attached to the 1st sling. If I was home i'd demonstrate.
Did you notice the Bren Mk1 in the 3rd photo (first lot) is an intermediate gun.
