There is a take-down pin made by KNS Precision called the KSG push button take down pin & QD sling swivel adapter. No screws. Push the button to remove the QD adapter, then push the button again to pull out the pin. I can't add a link because I am still a newbie, but "knsprecisioninc.com" will get you to the web site. Search on their site for "KSG"
