This Avery Easy-Off Back-Up Shotgun Sling is called the Easy-Off sling because it has SafDtach clips on each end for quick removal, and it's called the Back-up Sling because it has a holder for a shotgun shell for back-up!
This sling is designed for shotguns with permanent sling swivels. The Avery Easy-Off Back-Up Shotgun Sling has different versions of the Avery logo on each end. This sling is made from stretchable 7 mm neoprene and it has an ABT pad for maximum comfort. It has a tough DuraStretch facing, non-slip rubberized backing, and even comes with an ergonomic thumb loop. Total length adjusts up to 48 inches. Another great product from Avery.
Note: Sling does NOT have swivels.
