The ASAP QD (Ambidextrous Sling Attachment Point QD) allows a wide range of motion, enabling true ambidextrous weapon manipulation for both left and right handed shooters. Replacing the standard AR15/M4 carbine stock receiver end plate, the ASAP QD provides a tactical advantage by minimizing sling snagging and facilitating easy transition to and from weapon and reaction side shoulders. The ASAP QD works with one-point type slings with push-button quick disconnect sling swivels such as the MS4 GEN 2. Made from precision cast black Melonite(TM) finished steel and compatible with both mil-spec and commercial-spec carbine receiver extensions. Made in U.S.A. Features: Accepts any push-button QD sling swivel as well as the Magpul QDM Durable steel construction Case hardened and finished with Melonite(TM) for extreme resistance to wear and corrosion Works with both mil-spec and commercial-spec carbine receiver extensions (buffer tubes)
