The Trijicon MRO (Miniature Rifle Optic) SD is a sealed, miniature reflex sight intended for use on rifles, carbines, and shotguns to provide fast target acquisition. The MRO SD maintains the same durability and footprint of the original MRO with an enhanced optical design for pairing with magnifiers and night vision devices.

The MRO SD features a reengineered objective lens with advanced lens coatings that delivers a refined, crisp 2.0 MOA center dot, optimized for seamless use with the optional MRO 3x Magnifier. The MRO SD is also equipped with upgraded windage and elevation adjusters for improved zero retention under direct impact and heavy recoil, ambidextrous brightness controls, and a fully sealed, waterproof, hard-anodized forged 7075-T6 housing.

The Trijicon Miniature Rifle Optic (MRO®) SD Magnifier is a 3 power reflex optic magnifier specifically designed to magnify the target and target seen through the MRO SD red dot optic. By magnifying the target the shooter is able to use the crisp dot in the MRO SD to quickly and accurately engage targets at extended distances. The MRO HD Magnifier is short and compact which saves weight and rail space. The design features easy-to-set flush, toolless adjusters that make centering the reticle in the field of view easy. The adjustable diopter allows the user to tune the optical performance to their eyes.

The 3x magnifier also includes a multi position, military-grade flip-to-side quick release levered mount which makes mounting and unmounting the optic from the host platform quick and easy. This mount is also designed to flip into place over the top of back up iron sights commonly used on modern sporting rifles. Each magnifier includes a riser plate and additional fasteners to allow the optic to align with either 1/3rd or Full Co-Witness MRO SD mounts.
