Leupold Mark IMS Integral Mounting System Features The Leupold Mark IMS Integral Mounting System is purpose-built for AR-15/M16 rifles using a forward cantilever design that places the scope further ahead on the Picatinny rail to give the shooter a full unobstructed field of view. The mount s angled geometry adds 20 MOA of elevation extending a scope s usable adjustment range for long-distance shooting beyond what the scope s internal adjustment alone could reach. It accepts any scope with a 30mm maintube and locks directly onto a MIL-spec 1913/Picatinny rail with no gunsmithing required. This integral one-piece ring and base design eliminates alignment issues that can come from separate rings and bases. Placing the center of the optic 1.5 inches off the rail matches the sight height of classic AR iron sights making it easier to get a proper cheek weld and sight picture without straining to get low on the stock. At just 6 ounces the matte black finished aluminum mount adds minimal weight to the rifle while providing the rock-solid return-to-zero performance Leupold mounts are known for. Made in the USA and backed by Leupold s reputation for rugged dependable hardware the Mark IMS is built to secure a scope through a lifetime of hard use. For AR-15 and M16 shooters looking to solve mounting height and eye relief in one component the Mark IMS is a proven solution.
