Trijicon MRO 2-MOA Mini Rifle Optic w/ Low 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 Low Mount (AC32067)

    Great optic, poor packaging.

    Posted by Coty Allshouse on 21st Mar 2021

    I recently bought a Trijicon mro and thought the price was good, around $440. So I ordered it and when it came in the mail it was just in a basic cardboard box bouncing around on the inside. No lens protection or anything. The paper work was in a plastic bag just tossed in the box as well. I do t know if it came from arms unlimited boxed like that or from Trijicon. But I just thought it was disheartening when you spend over $400 on an optic and it comes bouncing around in a flat rate box. Other then that the Mro is fantastic

    Trijicon MRO

    once again AU has the gear I need at the best price. I already purchased x2 of these MRO red dot sights from AU in less than 3 weeks. I can look past the original black hardcase/box from trijicon. The sight is authentic and comes with everything that's supposed to come with the sight. I've already ran both MRO and they hold true. (I changed out the factory mounts on both MRO with scalaworks mounts)

    Great company w/ Personal attention

    Posted by Frank (Ret. LEO) on 25th Aug 2020

    after searching and trying to locate a Trijicon MRO- a “different” popular company took my order than the next day tracking said almost 2months delivery, as it was out of stock — I took a chance and Emailed AU, within 30 min. I was contacted back and they said - Standby 20 min., we are updating our Inventory, within 20 min as stated, I received an email with Trijicon MRO in stock- and to boot, was a better price.. long story short, I had the Trijicon in my house within 3 days .. This company may not pay for expensive marketing as competitors, but AU is the real deal....

    Great price, fast shipping and quality product. The sight did not come in the usual Trijicon black plastic box but appeared to be a new stock product. Bolted it to the low mount and then onto a rifle, works perfectly. Will gladly continue to do business with ArmsUnlimited.

    Great Optic! (and a little side note)

    Posted by Richard Veres / WV State Capitol Police on 12th Sep 2019

    This optic is THE BEST CHOICE for my MP5K PDW! When you unbox this little wonder you’ll notice the objective lens is mounted at an angle. I freaked and called Kathy at Customer Service to request a return authorization. She promptly sent me a reassuring email from Trijicon stating this was normal and was required for proper reflection of the red dot.

    top tier red dot sight, best price found

    Posted by BC Gideon C. Dengle on 31st Jul 2018

    After spending the better part of a week searching for the best price, AND the latest edition of this red dot, I found it here. Don't let the price fool you. This isn't some old inventory priced to move. This is the latest edition of the MRO. As for quality...I would trust my life to Trijicon. You cant go wrong with this optic for ANY platform. I am going to purchase two more, one for my combat shotgun, and one for another modern sporting rifle of mine. The platforms it will work on are endless.

    Quick ship, great price

    Posted by Scott on 19th Jan 2018

    This is my third MRO, and I got this one for an AK, along with the cover. Quick ship, packed well, though it did not come in the traditional Trijicon hard plastic case as others have. The price Arms Unlimited had on this at the time was the best I've ever seen.

    Great optic.

    Posted by JD on 18th Jan 2018

    The Trijicon MRO is a fantastic little optic for the price. I'm used to the more expensive and heavier options from Eotech and Aimpoint but this light little product from Trijicon does not disappoint!
