The Leupold Mark AR family of mounts solves both these problems while providing the most rock-solid mounting solution in the business. 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 the USA.
