Description
The Leupold Mark IMS (Integral Mounting System) is a cantilever scope mount engineered to address common mounting challenges on AR‑style rifles. It secures directly to Mil‑Spec 1913/Picatinny rails found on AR-15/M16 platforms and is designed for scopes with a 35mm main tube. The cantilever design raises the optic and pushes it forward to improve eye relief and overall sighting position without additional risers. Constructed from aluminum with a matte black finish, the Mark IMS is covered by the Leupold Full Lifetime Guarantee.
