The Leapers UTG Super Slim MRO® Mount is a Lower 1/3 Co-witness mount and includes MRO® Patrol Mounting Screws and Installation Tools. The mount is precision CNC machined from 6061-T6 aircraft grade aluminum and finished in a matte black and hard anodized. The Mount has a 0.86" Saddle Height that positions the MRO®/MRO® Patrol at the Correct Height for a Lower 1/3 Co-witness in line with Standard Height AR Iron Sights. It utilizes a locking Torx Screw and square-shaped Integral Recoil Stops for a secure Zero Hold. Significant lightening cuts reduce overall weight and bulk.
