The Mission First Multi-Use sling adapter is an aluminum sling mount that does not require disassembly of your lower receiver. The OPSM works with any AR-15 carbine receiver extension and is easy to install by removing buttstock and sliding the mount over the tube. The mount will work with web slings up to 1.25" in width, HK-Style Hooks, MASH Hooks, "Dog Leash" style hooks and small carabineers. The sling mount is CNC machined from aircraft aluminum and anodized in matte black.
