Sling swivels, studs and the screws that go with them.
- Quick-detach sets — Jack Pyke 1" QD swivels in pairs with screws, and in packs of ten if you are fitting several rifles.
- Silent — Quake Hush Stalker II swivels, designed not to rattle against the stock. Worth it: a clicking swivel is a genuine and entirely avoidable way to lose a beast.
- Studs — Quake long QD studs, including for fitting a bipod as well as a sling.
Check swivel width against your sling — 1" is standard, but not universal.
