Made in the USA, 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 made from Melonite finished steel for wear and corrosion resistance. It is designed specifically for use with legacy MOE hand guards and forends, has a low profile design, and has anti-rotation feature that prevent swivels from spinning. NOTE: MOE accessory slot must be enlarged by user to allow installation. Instructions and hole saw included, and a drill is required for install.
