Magpul M-LOK quick detach sling mount.  Accepts most QD sling swivels.  Includes anti rotation stops.

Professional Note:  This QD sling mount is one of the few we sell.  It uses two M-LOK recoil lugs, unlike most other market offerings, which use only one.  This insures the mount can never loosen over time and slide back and forth in an M-LOK slot.  A correct mechanical connection is achieved between this mount and the handguard slot.
