The BHI B-Tac Quick-Adjust Sling is constructed of heavy-duty, 1.25-inch wide Denier nylon webbing (versus one-inch straps common with competing sling designs) for enhanced weight distribution, and featuring a long, comfortable shoulder pad for maximum user comfort, the B-Tac Sling comes in two versions. Model numbers BH-000-009-CT (tan) and BH-000-009-BK (black) feature removable Quick-Detach (QD) swivels to allow the strap to be swapped between rifles with QD or conventional strap swivels. Model numbers BH-000-010-CT (tan) and BH-000-101-BK (black) have the QD swivels sewn-in to eliminate excess strap, making them compatible for use on any M4/AR-based rifle equipped with Quick-Detach mounting points.
