Fast Target Acquisition Every Time. The Trijicon MRO® (Miniature Rifle Optic) is a sealed, miniature reflex sight intended for use on rifles, carbines, and shotguns to provide fast target acquisition. It is designed to be used with both eyes open, providing the operator with maximum situational awareness.
The large aperture and tapered light path maximizes the viewing area in such a small optic, allowing for fast target engagement – especially from non-standard shooting positions. It also features ambidextrous brightness controls, sub-flush adjusters, advanced lens coatings, and a fully sealed, waterproof, hard anodized forged 7075-T6 housing, making the MRO the ultimate mini reflex sight.
The MRO HD is optimized for use with a magnifier, with a re-engineered objective lens to produce a refined 2.0 MOA center dot surrounded by a 68 MOA segmented circle reticle. The ambidextrous reticle and brightness control allows the user to choose between a full reticle or center dot only.
The Trijicon Miniature Rifle Optic (MRO®) HD Magnifier is a 3 power reflex optic magnifier specifically designed to magnify the target and target seen through the MRO HD red dot optic. By magnifying the target the shooter is able to use the crisp dot in the MRO HD 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 HD mounts.
