MagPul ASAP Receiver End Plate Sling Mount Adapter Ambidextrous AR-15 Carbine Steel Matte The MagPul ASAP (Ambidextrous Sling Attachment Point) allows for over 180 degrees of sling motion, for fully ambidextrous use and a wide range of motion. Designed specifically for use with single point slings employing a snap hook means of attachment, the ASAP minimizes binding when switching the rifle from one shoulder to another for smooth transitions around corners, during drills, or in the event of an injury. The solid steel ASAP features a welded link ring for strength, and replaces the standard AR-15 carbine endplate. Compatible with both mil-spec or commercial diameter buffer tubes.
