This PRODUCT SUUUUCKS!!!
Added to my VERY expensive Trijicon Dual Illuminated RMR. Second time I used it in a match the lower frame piece must have come off and the metal honeycomb screen came out (See attached photo) during a stage and screwed up my site picture and time!! I expected much more from Trijicon. It is cheap plastic. Shouldn't be charging $36 for it. Especially one that comes apart so easily. I maybe put 300 rounds through my 9mm pistol before this epic fail!! Haven't even had this kill flash a few weeks. UPDATE. After having this product for over a month now and used it extensively. I can truthfully say its TERRIBLE. I hate to say it about Trijicon (I love my RMR), but this is a HUGE waste of money. Sent my first one back to Trijicon and got a (timely) replacement, When I put it on and used it in a USPSA match same thing happened!!! Bottom frame came off, this time however I was able to find it after the stage. Super glued the plastic piece of garbage back on and that seems to have stopped the frame from coming off, but after a few more matches the whole piece started popping off!! WTF Trijicon!! I expect much more from you! Save your money. Has a little of the "tacticool" factor, but it doesn't work! If there were negative stars, this would get them.

5.0 out of 5 stars Fit Well on Dual Illumination
Reviewed in the United States on February 12, 2017

Bought two. Both came in original Trijicon package. Both fit and snapped on to a Dual Illumination RMR with no issues. U can see the honey comb and it will reduce brightness slightly. The trade off is u get some protection for the RMR and no sun glint off the RMR glass face. Note: the Trijicon factory package it comes in specifically says "Dual Illumination" as does the title of the ad. Not saying it won't work with other RMR models but don't be surprised if the fit is not perfect.

I'm a huge fan of Trijicon's products. I have several sets of their iron sights, two RMR's, and an ACOG. I am biased. That said, this product is a little bit of a letdown. While it definitely fits, seems tough, mitigates light reflecting, and is a legit Trijicon product.... It doesn't really stay put that well. I have not had a problem with it under 5.56 recoil yet, or general handling, but it does shift/move around during transport in a range bag. (the RMR is on an AR with an offset mount). Just something to be aware of. I'm still trying to figure out how to creatively secure it better in a way that's not "permanent" and I'm still giving it 4 stars for now. If it has issues at the next training class I attend, I'll update this.

These snap on very snugly to a dual illuminated RMR with no movement once it's on and work great to reduce/eliminate the bright orange reflection off the front lens of the RMR. It also helps to prevent contact that could scratch the coating on the front of the lens. They fit snugly enough that any force that could unintentionally knock this off the RMR would potentially shift the POA.

5.0 out of 5 stars Expensive but still great
Reviewed in the United States on September 3, 2014

I searched for reviews for this all over the internet and could not find a single one. Because it was expensive I wanted to find out if its worth the price. Everywhere I looked had about the same price for this item $45-$55. Once the price dropped on Amazon I got it. The details state that its Aluminum but in fact its only the honeycomb that is. The outside frame is plactic. For the most part its solid except the bottom feet. Those have some give which could break if it were acidiently stepped on. Once its installed its fairly secure, the feet have a lip that attach on the groves of the RMR. Once you look through the RMR you can see the honeycomb slightly probably because its so close. No issues other then the price. I dont think the cost above $50 is worth it but it definitly worth getting once the price is reasonable.

5.0 out of 5 stars Best RMR cover on the market.

This is the second time I purchase this item, two different experiences. The first one I bought was flimsy , it would bend when slight pressure was given and once attached it snapped off so easy a flick could knock it out. I ended up throwing it away. Somehow while looking for protective options, I was always led back here with the best idea for the rmr protection, so I bought it again. This time it was hard to snap it on, once on, the product is flush. It seems as it's one piece and it doesn't seem to want to come off without a tool now. It is of superb pmag polymer style plastic, the front mesh is metal and thick. Honestly just buy it, try it out, I'd buy two from two different websites and keep the one that fits best. So it's a hassle but when you get the right one, you won't look back.

3.0 out of 5 stars I think this RMR Tenebraex shield will work fine with my RMR LED sight after a slight modification

I think this RMR Tenebraex shield will work fine with my RMR LED sight after a slight modification. The unit partially covered the ajusting buttons. A small Dremel sanding drum allowed me to reduce the material to expose the buttons. Works fine now. Be careful and take off a little at a time as you can’t put the material back once removed. Trijicon should have made one for the LED as well as the Dual Illuminated Model.
