The MRO has come a long way since its initial release. The MRO HD gives you a choice between a standard 2 MOA single-dot reticle or a 68 MOA ring with a 2 MOA center dot giving you some EOTECH vibes in a more traditional style reflex optic. It also features a large sight picture, decently clear glass, and top-mounted brightness controls. Trijicon optics are known for their ability to take serious abuse, and the MRO is no different with a forged 7075 waterproof housing.

The MRO HD does not come with a mount. We recommend the Scalarworks LEAP/05.

Why the MRO? Weren’t there issues with the original?
While we weren’t huge fans of the original MRO because of its parallax issues and slight magnification, the MRO HD has fixed those issues and added some new features along the way. This also adds another layer of redundancy to our ever-growing product lineup.
