Rival Arms QD Rail Mount Swivel Features The Rival Arms QD Rail Mount Swivel addresses a common gap on M-LOK equipped rifles that were not built with a factory quick detach sling socket. By mounting directly into standard M-LOK slots it adds a reliable QD attachment point without requiring any permanent modification to the handguard. The recessed button design keeps the swivel low profile against the rail reducing the chance of snagging on gear clothing or brush while moving through the field or on a range. This style of attachment has become one of the most popular methods for mounting slings because of the speed and security it offers compared to traditional sling loops. Because the kit includes both the QD sling swivel and the mounting socket shooters do not need to source additional parts to get a complete setup. At just 0.11 pounds the swivel adds negligible weight to the rifle while providing a dependable attachment point for a two point or single point sling. Its black finish matches most M-LOK handguards and rail systems for a clean factory look. The Rival Arms QD Rail Mount Swivel is a simple effective upgrade for sale at GrabAGun for shooters building out their M-LOK rifle.
