The Magpul QDM is a heavy-duty upgrade to standard push-button quick detach sling swivels. The innovative design fits all standard sized QD cups and allows for a lower profile sling swivel that offers one-handed manipulation, a high strength bale that rotates freely, canalizes sling webbing to prevent rollover, and superior resistance to corrosion with a Melonite finish. Dual side release tabs prevent accidental release.
