    Trijicon MRO cover

    Great cover for a great optic. I definitely needed a blow dryer and a pair of wooden chopsticks to fit the cover over the optic, but great fit. Lens covers nest into each other with a firm snap, so definitely not coming apart when shooting. Excellent!

    The product is great. I have read some reviews with people saying it was impossible to get on or they had to heat and melt the cover to get it on...This is total BS and if you had to do all of that to get the cover on maybe you should reconsider owning the optic and firearm you are mounting it to....I suggest that anyone who is having a hard time goes to YOUTUBE and watches an installation video. It took about 2-3 minutes for me to get it on. You shouldn't have any issues as long as you don't have little baby hands! This is a great product and I will certainly be buying other products from TangoDown in the future!

    IO Cover for MRO

    A little tricky to stretch onto the light (watch the YouTube) but once on, it's not coming off and provides very notable protection to expensive optics. Indispensable.

    Good shipping time. Great fit and looks good. Installation is easier if the cover is warmed with a blow dryer on medium heat for a minute or so before slipping on.
