The ULoop brings a level of versatility to sling hardware. 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. Theres no need to have multiple sling attachments. Fits HK, AK, SIG, SCAR or other eyelets. Can be mounted through holes in handguards and through KeyMod systems. Fits slings up to 1.25" wide and also fits the Vickers Combat Applications Slings. All ULoops have 1" wire loop as measured from the base of the sling loop to the top of the loop.
