This sling is a correct representation of the military sling for the AR15/M16. It is fully adjustable, black cotton web with a swivel hook. May also be used with the Jungle Sling adapter. 1-1/4" sling has an adjustable length from 26" to 52".
To mount the sling on the rifle, take the hook end and attach to the sling swivel on back end of gun stock. Open sling keeper (clamp) and pull the sling out straight and feed through the front sling swivel on gun, then re-slide the sling back through the sling keeper (clamp) and lock down. This is also how the sling can be adjusted for length.
Hook sling attachments require a hook sling mount on the rifle (not included)
