I, like many others keep the Rattler slingless in the bag but carry a sling with me in case I need it. I found that a traditional QD swivel would block my thumb from efficiently working the selector. Searching the webz, I found this at Grovtec. Much more room to access the safety and seems rock solid like all of their stuff. A tad narrow, but a 1-1/4” BFG sling fits.
