Leupold Mark 4 AR Scope Mount Features The Leupold Mark 4 AR Scope Mount is CNC-machined as a single piece combining the base and rings into one strong lightweight unit rather than relying on separate components that can shift independently under recoil. Built from aluminum it is designed to be strong and exceptionally durable even under the repeated impulse of extended range sessions. Its 30mm ring diameter accommodates a wide range of modern riflescopes that have moved to the larger tube size for increased internal adjustment range. A matte black finish keeps the mount s appearance consistent with most AR builds while resisting glare that could otherwise draw the eye off target. Designed specifically for AR-style rifles with a standard Picatinny MIL-STD-1913 rail the Mark 4 solves two problems that plague aftermarket scope mounting on ARs namely getting proper scope height and achieving correct eye relief for the shooter s cheek weld. At 5.43 in length and a super high 1.40 ring height the mount is sized to clear large objective scopes while keeping the optic s centerline at a usable height above the rail. Weighing 6.05 oz it adds minimal bulk to the rifle while providing a rock-solid mounting platform.
