There are two common issues when mounting scopes to AR-style platforms getting the right scope height and the eye relief. The Leupold Mark AR family of mounts solves both these problems while providing the mounting solution. Combine that with ease of a one piece mount and you have the perfect match to that precision Leupold scope. The Mark AR mount features a 5 bolt design for a secure hold, 3 lugs on the bottom any kind of recoil and a STANAG fit which means more contact area with the Picatinny rail for an exact fit. Made in USA.
