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

    Just as expected

    Packaging was great, fit was perfect, the FDE was a little lighter than I had hoped...but it still look good with my FDE furniture. Shipping was very fast also

    I have several MROs and thought I would give this a shot. Glad I did. Works great! Arms Unlimited shipping was super quick and professional.

    Really tight fit but once on it wasn’t really tight to the body but works.

    Another good experience

    I’ve ordered multiple times from AU. Everything from suppressors to ammo and firearms. I’ve always had a no hassle experience and one that I’ve come to expect and you should too.

    Optic Cover

    Posted by Jonathan Wiese on 24th Sep 2020

    I’ve been looking for one of these optic covers for sometime. Arms Unlimited had a great selection and the FDE color to match the rifle. The price was amazing and shipped right away. The cover is sturdy and will protect the optic from major damage. The clear caps are a nice touch and you can use the optic with the caps closed if your in a pinch. Great product and great experience with the purchase.

    Good fit!

    So, I was shipped the Trijicon brand cover, not the iO (Tango Down) cover, but that's ok because it fit real well. Takes some patience getting it on which is good because it fits well and looks good!

    Great price for an OEM cover.

    Great price for an OEM cover. Fits nicely and protects the dial from impact and accidental adjustment.
