Ever have an issue with your rifle tipping backward when you sling it onto your back; or worse, you finally got a new suppressor and now the balance is off. This adapter uses the existing 10-32 sling studs in your stock to move your sling attachment point forward (Stud & QD). the bottom has a radius to keep the adapter stable. The ARCA section allows a bipod or a tripod to be mounted. The adapter weighs 2.63 ounces and comes with (2) 10-32 screws for installation. The inside spacing is 3.7 inches. please measure your existing sling stud spacing to insure proper fitment.
