The GRS 1" Pushbutton Sling Loop is a heavy-duty, quick-detach (QD) swivel designed for the rapid attachment and removal of rifle slings. Precision-machined from high-strength steel with a manganese phosphate finish, it is engineered to withstand the rigorous demands of field hunting and tactical applications. This loop is a perfect match for GRS stocks equipped with flush cups, such as the Bifrost, Warg, or Fenris, as well as any other standard flush cup mounting point. The pushbutton mechanism is designed for tactile, one-handed operation while maintaining a secure, anti-rotational lock to prevent sling tangles.
