This MagPul Forward Sling Mount allows for the use of many different styles of tactical sling on the Mossberg 590A1 shotgun. This mount was specifically designed for the heavy walls on the barrel of the 590A1 series shotgun. The sling attachment point is machined into a barrel clamp which attaches to the barrel and extended magazine tube. You can also configure this sling to accept Push-Button QD sling swivels or one-point clip-in style attachments such as the MS3 Paraclip, the HK Hook, ITW MASH hook, and many others. The precision cast steel is the Melonite treated to provide rugged durability that will stand up to years of wear and provide corrosion resistance for use in harsh environments.
