The Mark IMS Mount is Leupold's newest top-of-the-line mounting solution for scopes with a 35mm tube diameter. The Mark IMS family easily eliminates the two most common issues faced when mounting standard riflescopes to AR-style rifles; scope height and eye relief. This model is designed to fit your AR's MIL-spec 1913/Picatinny rail. The Mark IMS Mount's one piece machined design makes it incredibly strong and rugged ensuring the mount will preform flawlessly even under the most brutal conditions. The mount uses a heavy 2 bolt design that allows for quick and repeatable installation and removal.
