Magpul MAG337: RSA QD (Rail Sling Attachment)
The Patented [ US Patent No. D652,887 ] Gear Sector™ Rail Mount QD Socket provides a forward mounting location for those who wish to utilize our two- or three-point sling with our QD push button adapter. We designed the mount to fit perfectly flush with the Tango Down rail panels to provide an uninterrupted rail space. The socket was designed and machined to prevent rotation, which in turns prevents your sling from becoming twisted.
The Gear Sector™ Rail Mount QD Socket is precision CNC machined from billet 6061-T6 aluminum and finished per Military Specification ( MIL-A-8625F ) Type III, Class II Hard Coat.
Installation is straight forward. Simply loosen the socket head cap screw. Remove the screw/clamp assembly. Apply a drop of Vibra-Tite® VC3™ ( included ) to the last few threads and allow to dry. Slide the mount onto your rail system, insert screw/clamp assembly and tighten it down with the included allen wrench.
