Trijicon Mro Levered Q.r. Lowr 1/3 Co-witness Mount Picatinny. It is designed to mount in the lower receiver to allow the use of a traditional rifle scope with a reflex sight mounted in front of the rifle. The smaller the overall profile of the rifle scope the greater the field of view. The MRO mount is constructed of a single piece of billet aluminum and mounts rear sight at a canted position reducing potential for issues such as sight shift. The mount is constructed of an aluminum alloy heat treated to withstand heavy use while the mount is rugged and shock resistant. The mount is designed to fit the Trijicon Miniature Rifle Optic (MRO) only. It will not fit a reflex sight such as a HRO RMR or Aimpoint. Specifications for Trijicon Mro Levered Q.r.
