The Phase 5 revolving sling attachment solution (REVO-SAS) is an ambidextrous rear sling attachment solution that moves from left to right freely, smoothly and quietly. The REVO also has patented technology developed to internally limit the amount of rotation and eliminates external obstruction issues completely. The REVO-SAS is machined from billet steel for maximum strength and durability.

Features:

• Patented technology - unique design maximizes smooth, quiet left-to-right action and internally limits rotation
• Phase 5 custom-machined proprietary castle nut included - hardware allows sling attachment to fit Mil-Spec buffer tubes
• Billet steel construction - rugged material allows for maximum strength and durability
• Mil-Spec phosphate finish - ensures aesthetic uniformity, and stays true to military standards of material coating
