## Questions & Answers

**Q: Will it work with the trijicon rmr ?**
A: Do not know but it works with Vortex Viper

**Q: Will this fit the ade red dot?**
A: It should

**Q: Will this co witness with a vortex venom on a glock19 gen 3?**
A: Yes. I have a Venom mounted on a Glock 41 using the CoWitness mount and it works fine.

**Q: Does this come with the screws?**
A: Do not remember exactly if it comes with screws. But your optics must have screws for different mounts and you may use that. Mounting holes for optics of this type (rmr) is popular, bought optics must have one.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Abit costly but well worth what you receive. Maintained zero and extremely happy with purchase.
*by A***A on October 20, 2019*

Ok, so first off, as you can see from the pictures, the sight is amazing. Mounted on my glock 19X and could not be happier with how it turned out.I work private security so I am looking to always have an edge incase things hit the fan. Red dots allow fast sight picture but I dont want to give up my iron sights incase all else fails. This allowed me to have what I needed.I took it directly to the range for a zero and the sight did not disappoint. Had it professionally mounted by my gunsmith at the range and he was very impressed with the construction of the mount and how sturdy it was.The tritium night sights is a must have if you are serious about buying one of these. I do wish the price was lower, but if you're gonna spend the money to get a cowitness mount like this, you might as well spend alittle more for the tritium. As you can see from the pictures, they work amazingly well.Now, I will say keep in mind the THICKNESS of the back of your red dot. I initially tried a ADE advanced optics red dot with this mount and it was too thick to use the iron sights properly. The whole point of this mount is to have the BEST OF BOTH WORLDS. So i switched to a vortex viper and as you can see, it worked beautifully.Last thing, the mount IS NOT like in the picture when it arrives. In the picture it shows the mount will have a sort of "stabilizing posts" to slip into the corners of the red dot to make sure it is sturdy. Mine did not come with this. I am assuming this is because of of how the variety of red dots can change in size, it was best to leave it off.Either way, after 500 rounds down range, I had NO ISSUES. Mount and the sight both stayed sturdy and maintained zero.

### ⭐⭐⭐⭐⭐ Excellent design
*by E***G on January 9, 2019*

This thing is rock hard and tougher than nails. After attempting to use a cheaper adapter for my red dot on a Glock semi-auto pistol, and having my red dot slap me in the forehead, I decided maybe I needed to rethink my adapter. Bought this item, which definitely took some coaxing to install on the gun (it's a tight fit and the metal is really hard - had to use a hammer and a vice). I am QUITE confident this one is not coming off.What's even better it that is has a set of co-witnessing sights built right on it, painted with tritium dots, so I can swiftly aim the gun in very low lighting, without having to be concerned that I haven't had time to turn on the red dot. I can plainly see where I'm aiming. When I do have time to turn on the red dot, the adapter's sights allow me to quickly find the dot, whereas before, it was a bit of a treasure hunt; obviously, with the rear sight removed, the front sight is now rendered useless for aiming. This adapter replaces those sights, and although the length of the physical sight no longer allows for accurate distance aiming, it is perfectly suited for quick aiming at close range. Furthermore, the red dot really allows for very accurate longer distance aiming, if you have time to place the red dot on your target. (I mean this adapter's built-in sighting is Really quick, once you get used to it!)

### ⭐ It’s not worth the money!
*by K***G on February 29, 2020*

Product only lasted after using it twice and then the dovetail mount came loose and could not be tighten. It’s not worth the money.
