The Geissele Automatics GROVTEC Black Heavy Duty Push Button QD Sling Swivel is a professional-grade, American-made sling attachment solution built for demanding tactical and sporting applications. Constructed entirely of heavy-duty steel and machined to extremely tight tolerances, this quick-detach swivel locks securely into any standard QD sling socket and releases instantly with a single press of its large, tactile push button — even when wearing gloves.

Every unit is pull-tested to over 450 pounds of tension, ensuring reliable performance under the most rigorous conditions. Finished in a non-reflective Manganese Phosphate matte black coating, the swivel resists glare and corrosion while maintaining a low-profile, professional appearance. Whether for duty use, competition, or field carry, the GROVTEC Heavy Duty QD Sling Swivel delivers the strength, speed, and dependability that Geissele Automatics is known for.
