The Quick Detach Agency Rear Sling Attachment easily and securely fastens onto the castle lock nut versus the tube so various size recoil tubes are no longer an issue. The QD Agency Sling Attachment installs without removing the castle nut and no tools are required except for the included 9/64" wrench to tighten the fastening screw. The ergonomic design does not interfere with the charging handle operation, even the larger units like the Gas Buster.
