Ambidextrous Sling Attachment Point for quick-detach swivels adds a centrally located socket at the rear of the receiver. More than 180° of sling movement enables both left- and right-handed shooters to quickly shift their weapon between shoulders, plus the mount cup is angled slightly downward for greater freedom of motion and to create a finished look. Low-profile design includes rounded edges that minimize snagging. Constructed from durable, case-hardened, precision-cast steel with a Melonite™ finish for extreme resistance to wear and corrosion. To install, remove the standard AR-15/M4 carbine stock receiver end plate and slide on the ASAP-QD. Works with one-point type slings with push-button QD connectors, like Magpul's MS4® Dual QD GEN 2 Sling, as well as the MS1® Multi-Mission Sling with a QD loop assembled on back. Slings sold separately.
