How It Compares

This mount is cut for the Trijicon MRO, so it takes the Trijicon MRO HD, the Trijicon MRO SD Patrol and the Trijicon MRO HD Patrol. The same mount is also stocked as AD-MRO-LW at lower 1/3 co-witness and AD-MRO at low. For an RMR or SRO take the AD-RMR-LW mount; for a Holosun AEMS the AD-AEMS mount; for a Holosun 509T the AD-509T mount. our guide to co-witness heights covers which height suits which rifle, and our Trijicon buyer's guide puts the MRO in context.
