Hogue PolySwivel sling swivels are manufactured from a high-strength polymer for maximum strength and durability. In fact, they have a breaking strength far in excess of the force normally required to pull apart conventional steel swivels. They will not rust and are super quiet. The quick release stud easily attaches to standard swivel studs. Poly swivels are a perfect addition to your existing stock or your new Hogue OverMolded stock. Available in two sizes to fit 1" or 1 1/4" sling straps.
