GrovTec US GTSW108 Quick Detach Fixed Swivel Adaptor, Black Aluminum Base-to-Stud

The GrovTec US GTSW108 Quick Detach Fixed Swivel Adaptor is a no-fuss solution for hunters and shooters who want to add sling attachment flexibility to a rifle without permanent modifications. This aluminum base-to-stud adapter bridges the gap between a standard swivel stud (the kind most modern rifles use) and a quick-detach sling swivel, letting you swap slings in seconds or run your rifle without one. It's the kind of practical detail that makes a difference in the field, whether you're hunting, running drills at the range, or building out a tactical setup.

Built from aluminum with a Type III black anodized finish, the GTSW108 is tough enough for hard use and won't scratch or mar your rifle's stock. The fixed design (not adjustable, unlike GrovTec's GTSW235 model) means once mounted, it stays put—no wobble or play to work loose during a hunt or training session. Installation is straightforward: it threads onto your existing swivel stud, and you're done. No gunsmithing required.

If you're running slings on multiple rifles or want the option to move your sling between guns without tools, this adapter keeps things simple and reliable. It's the kind of understated accessory that serious hunters and shooters forget they can't live without once they've used one.
