The GG&G Shotgun Front Sling Attachments are made for both the Remington 870 and Mossberg 590 series shotguns. Both attachments are fully ambidextrous. Many competing products are manufactured from insubstantial stamped sheet metal and have rather sharp edges that not only can cut the sling, but can cut the operator as well. The GG&G Shotgun Front Sling Attachments are machined  from AS-35 Geneva steel. Of exceptionally high quality, this famous Swiss steel features molecular structure with elongated grains for added toughness. The corners have been rounded and dehorned for the operators safety. A ball bearing detent on the Sling Attachment helps secure the unit behind the magazine tubes end cap. Both versions are manganese phosphated.
