iO Cover for Trijicon MRO w/ Clear Caps | Flat Dark Earth


Protect your Trijicon MRO lenses with the iO cover. Featuring clear caps that allow you to see your dot and target while simultaneously keeping your lenses free of rain, snow, mud or other debris. The integral lens covers and protective armor body fit like a glove that can’t fall off or get lost. The low profile design allows covers to be quickly operated with one hand and nested together so they don’t flop under recoil. The iO cover is constructed from durable thermoplastic polyurethane so your optic will be protected from scratches, fingerprints or any other damage to both the housing and glass lenses.


  • Keeps optic body & lenses protected in extreme, harsh environments
  • One handed operation, covers nest together to prevent snags
  • Durable thermoplastic polyurethane material resists solvents, oils and UV exposure
  • Clear "see through" caps protect your lens while allowing you to see your dot

    Perfect fit for MRO

    Cover fits great and the clear caps ensure the glass on the MRO is protected when storing or moving the gun. Protects against most things that you'd experience at the range or in transit.

    Better than anticipated!!!

    Posted by Alex Hernandez on 5th Dec 2019

    I purchased this cover for an MRO Patrol. According to Trijicon and IO, the cover is not made for that particular model optic because of the flip covers. The rubber cover's molded lens covers need to be cut off and can be without damage to the actual cover. It fit perfectly! At a great deal from AU, it was a no brainer for me. Great price! Great product! Great service!!

    Good option to protect a pricey purchase

    Posted by Unknown on 7th Jul 2019

    I really like the iO cover for my MRO. Great fde that blends well with magpul and the fit is top notch. The lenses are decently clear but nowhere near as clear as the glass, which was expected. Also, pretty sure this is OEM trijicon gear because trijicon was on the packaging but this was way cheaper than buying from trijicon or getting the branded version.

    A must have

    Fits like a glove. A little on the pricey side for what it is, but hey, it's got Trijicon on it. Do yourself a favor and make sure you have a heat gun handy to help soften it up for easy stretching.

    IO cover

    The caps come attached and stow away by being snapped together on the side of the RDS. Not the best design IMO! But, a couple quick snips with an exacto knife and you have a great cover to help with the longevity of your optic and it ads a little color which is cool too!
