Leupold Mark 4 AR IMS 30mm Matte

The Leupold Mark 4 AR 30mm Integrated Mounting System (IMS) provides a dedicated mounting solution for AR-pattern rifles and optics with a 30mm main tube. Its CNC-machined one-piece base and ring design is made to interface with standard Picatinny (MIL-STD-1913) rails and to simplify proper scope height and eye relief on the AR platform. The design emphasizes secure, repeatable alignment between rifle and optic for tactical and precision applications.
