QD cup problems

[PAcondor]

I have a Springfield waypoint that i can not find a sling that will snap into the cup on the stock. Last one I tried the top plug pulled out and I dropped the muzzle on the concrete floor. Now I have a song up muzzle break. Anyone have any suggestions or solutions?

Which ones did you use? I think most people I’ve seen on here, including myself, are using the Grovtec’s. I know they fit tight on mine and feel secure.
