The Proctor two-point adjustable gun sling was designed to meet operational needs efficiently with minimal bulk and without the need for attaching hardware. The Proctor Sling comes with everything needed to attach it to a wide variety of guns. The Proctor Sling attaches to the rifle using the supplied 550 cord loops. The Proctor Sling can also be attached using any sling loop or Q.D. mount, however it is recommended to use the supplied 550 cord loops as they allow the sling to be mounted with minimal bulk and excess weight. The front 550 cord attaching loop cinches around the rifle forearm with no bulk or pivot points added to rifle. This is critical when shooting the rifle from the side gun position from behind cover that you may be using for stability. The Proctor Sling is fully adjustable and excess webbing stores on itself, so there is no need to tape up excess webbing. The Proctor Sling has proven to be effective, durable and strong.
