Don t leave your rifle system's accuracy to chance. The Leupold Mark AR line of mounts addresses the two common issues of mounting scopes to AR-style platforms - proper height and eye relief - while providing the most rock-solid mounting solution in the business. Combined with the ease of a one piece mount, the Mark AR mount has the perfect match to your precision Leupold scope. The Mark AR mount features a 5-bolt design, with three lugs on the bottom fir a secure hold through any kind of recoil, and a STANAG fit. That means more contact area with the Picatinny rail for an exact fit.
