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

    As described, looks and functions well

    I don't know if this is actually "needed" but it gives a little extra bump pro and possibly lens rain pro. As described, fits tight, looks good. It's not fun getting on, but once on it's rock solid.

    Trijicon MRO IO cover

    The cover is awesome. The guys at Arms unlimited shipped my item quick. I couldn't find anyone else selling the cover for cheaper. Arms crew emailed me when they first came out. Seemed to be fate since I had been in the market for quite a while looking for a cover. Thanks Arms Unlimited.

    Only Concern

    Was that Trijicon did not put the instructions in the product, thus delaying the shipping to end users. Otherwise a good product!
