The ULoop brings a level of versatility that is unmatched by any other sling hardware. Code named the ?Uber Loop? it is a quick-detach version of our popular Universal Wire Loop, offering even faster and easier installation, especially on smaller eyelets found on HK, SIG and FN weapons. The ULoop can be installed almost anywhere - through eyelets, holes in railed handguards, and on KeyMod rails. There?s no need to have multiple sling attachments. The ULoop replaces all hooks, clips and connections..
