The MSA QD (MOE Sling Attachment QD) attaches directly to MOE Hand Guards and Forends, providing a forward sling attachment point for push-button QD slings such as the MS4® GEN 2. The MSA QD is case hardened and made from Melonite™ finished steel for wear and corrosion resistance. Its anti-rotation feature prevents swivels from spinning. Designed specifically for use with legacy MOE® Hand Guards and Forends.
