Trijicon MRO 2-MOA Mini Rifle Optic w/ 1/3 Co-Witness Mount

Bulk Packaged from Trijicon


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. Advanced lens coatings and electronics produce a crisp red dot.

The brightness control dial on the MRO is specifically designed for ambidextrous usage. With a mid-adjustment “off” position and eight discernible brightness settings, this brightness dial allows for quick and ergonomic adjustments.

The MRO features fully protected adjusters that maintain zero even during rough handling, and can be adjusted without the need for special tools.

Hard-anodized, forged 7075-T6 housing is fully sealed and waterproof, providing durability in demanding conditions.

  • 1 MRO Lower 1/3 Co-witness Mount (AC32069)

    Works Great; No box

    Posted by Mitchell on 17th Aug 2020

    Everything works great which is the most important thing but I was not expecting the optic to show up loose in the shipping box. AU does say it is bulk packaged in the item description but I was expecting some sort of protection for the optic.

    I'm blown away by the quality of this optic. I used a Trijicon ACOG while I was a Security Forces member in the Air Force and used my knowledge from that optic to make this purchase. I beat the hell out of that Trijicon and it still kept going. I would defitnately recommend this to anyone who wants quality without breaking the wallet. -E.R. (Ret.) US Air Force
