Trijicon MRO HD 2-MOA Mini Rifle Optic w/ Full Co-Witness Mount


The Trijicon Miniature Rifle Optic (MRO®) is a reflex-style, sealed 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.

    Better than eotech!!

    Posted by MJP9 on 30th Oct 2021

    This thing is built like a tank. The upgraded reticle lets you switch between a single dot or the dot with broken circle (similar to eotech). The reticle is super bright even on a sunny day. The main selling point for me was the Night vision comparability. The reticle has several brightness settings that work great with my PVs 14s. The reticle is crisp with my NVGs and even with my vortex mini 3x magnifier. I am tempted to replace my aimpoint and delta point red dot sight on my other rifles…. Maybe if arms unlimited gives me a discount code. Anyways, if you are in the fence about buying one, just pull the trigger. You won’t regret it. Also, if you plan on running a magnifier or weapon mounted Pvs 14s, get the full co-witness mount.
