Review: Worked perfrctly - Fit perfectly.
Review: The Wait is Finally Over !!!!!! - All I can say to Trijicon is "it's about time". I'm so thankful that the company has put out a cover for the MRO that is of high quality with regard to fit and finish. Even though this particular model can withstand everything short of a bomb, this cover really gives it a second layer of protection. The lens covers are very welcome addition. I previously had to rely on Butler Creek scope covers of which I could only use one for the front as I could never find one for the back that would fit. The scope cover offers the opportunity to leave the lens caps on without having to remove them to shoot through. Usually adding another lens of some type may create some distortion, but not in this case. Trijicon chose their materials wisely in the making of this product. All the controls are fully accessible without any kind of hindrance from the cover. I have just a few cons regarding this product and they all relate to installation. The lenses are smartly packaged and have covers to protect them from scratching which are extremely difficult to remove. This may just have been the case with mine alone but I hope you have a good set of fingernails and some patience. Had to rely on my wife to remove the film that covered the lenses (right after she got he nails done a few hours before). She lovingly cooperated for her gun nut husband. Putting the cover on was somewhat of a minor fight. The end product is fantastic but getting this cover on your MRO is not going to be something that you're going to do in 30 seconds. Then again you may,so if you did please post up on how you did it. I'm going to be running my rifle this weekend to determine whether in fact the lens covers can stay on and not have my vision distorted while I run and gun. If they don't function to my liking, I will just fold them onto the side and keep on trucking. No more searching for aftermarket covers and lens caps for this guy. I'm very happy with this product. Get you one, you won't regret it. BTW it's about 10 bucks cheaper on desertcart than the Trijicon website.

## Questions & Answers

**Q: Are the lens caps clear or opaic?**
A: They are clear.
They’re NOT INSTALLED from the factory...You’ll need to peel off protective film and snap them into into place.
BUT BE CAREFUL to NOT remove that film until they are SNAPPED IN!
Or;You can very easily cause light scratches like I did!
I have 2...it went better the second time.
Of course US GUYS DONT ALWAYS READ INSTRUCTIONS! lol
I recommend these highly..
Both the MRO & the cover!

**Q: Will the front cap work with the ARD installed?**
A: Unfortunately no. The diameters are identical

**Q: will this cover work on the mro patrol?**
A: No it will not, it even says it on Trijicon’s website.

**Q: how do i remove the lens protection？  it seems like it can be removed**
A: You can remove the lens covers the clip them to the side. But you can just leave them on it's the same thing. Or you can blacken the front sight window to make it like the aim point pro.

### ⭐⭐⭐⭐ What else are you going to do?
*by A***R on April 7, 2017*

I'm glad they finally came out with something like this for the MRO if anything. I had no difficulty at all installing ours, you just need to take it slow and look where you have room to stretch. The fit is excellent and you can definitely tell it will be a nice little extra layer of protection from bad scrapes and hits. I am only deducting one star because of the price. I bought mine from the warehouse deals and it was still just weirdly high for what this is. Not at all Amazon's fault and I still love trijicon, but come on. Also, I'm not sure how I feel about the lens caps. I don't fault the maker of the product on this one as I don't have a better idea, but they're kind of just...in the way. Kinda thinking of just cutting the caps off as I mainly bought this as a bit of a buffer for the sight itself.
