Viridian RFX, Green Dot Reflex Sights, 3 MOA Dot, Shield RMSc, Docter and RMR Mountings, Includes Picatinny Mount

Very good optic. It is hard to find a 3 MOA Green Dot optic but Viridian has this one at a good price. It has a 30,000 hr battery life, shake awake and auto shutoff and brightness built in. I recommend it for pistols. I now have 2 of them and they work as advertised.

Got this and was a little bit skeptical that it would be a quality green dot, but this thing works great. Not only does this look great on a Taurus gun because it has the Taurus logo, it has a crisp Green Dot. The fact that it comes with the picatinny rail adapter so you can use it with any picatinny rail makes this a no-brainer.

Several key points why this product exceeded my expectations... The instant on feature is now considered by me to be a must have feature, far exceeds my other dots red dot sites, from Burris and Vortex. Outstanding brightness control and crispness of the green dot. Significant to me is I can see the front sight through the viewing plane with the green dot visible. This has two advantages, it makes it extremely easy to locate the green dot quickly, and it does allow some degree of co-witnessing. Another huge advantage for me is use with a laser dry fire cartridge, which projects a red dot and allows instantly visible comparison contrast with the green dot in the site. This make dry fire practice much more effective. One possible downside to the design battery replacement requires site removal, and this may have an impact on water integrity, But overall, it is much improved past sites that I've owned... and at half the price of other sites... Can't beat it with a stick!

Low deck height for a more compatible co-witness. Holds zero on my ported M&P 2.0 Carry Comp. Ports being in the slide cut, putting them closer to the chamber/Optic than the muzzle.Didn't realize the battery it came with was almost dead, the LED emitter flickered while shooting about a month into using the RFX35 on the weekends. Swapping out that battery for a Duracell 2032 solved that.Ordered a RFX11.

UPDATE: I've contacted Viridian and they will replace my unit - so kudos to their customer service and how they handle things. I will now test this that will be the third unit in a couple months - If it works, and lasts longer with a descent brightness level, I will update my review here as well.<Original Review>I'm competitive shooter, and color blind with strong protanopia, so I see a lot more green than red - I had my hopes high when I saw that this one has the same footprint as the RMR SRO (the window is a bit smaller, seems to be the same as the C-MORE RTS2), and it's green.At first it did seem to have a good brightness - not the crispier dot by the way, nothing compared to the high end brand such as C-MORE, RMR and Holosun. But the first unit I got broke even before I shot the gun for the fist time with live fire. I had it installed and was dry-firing a lot to get used to it. When I went to the range to do a live fire test for the first time, the brightness was already down, so I thought of changing the battery. After I removed the used battery and put a new one the thing wouldn't come alive again. It was dead! Tried the used battery again, nothing... 2 other brand new batteries, nada... It was dead.Sent the one back and got another one - The new survived the battery change, and I was finally able to test it for real - In a bright sunny day, you can see the green dot, but is not nearly as bright as you would like. Even on the maximum brightness and with a new battery, it's just not enough. And good luck if you shooting something with a white background... your dot will just vanish blending with the background because there is just not brightness enough to stand it apart.I can no longer return this one, or I would. I'm going back to the SRO. Even as a color blind and with extreme difficult to see the right amount of red, I can still work with SRO better than I would with this viridian thing.

The RFX15 is by far the best red dot I've found for astigmatism, providing a much sharper and more defined reticle than anything else I’ve used. The clarity is impressive, making it a standout choice for those who struggle with blurry or distorted dots. (However, astigmatism affects people differently)That said, the fitment was a bit unusual. Mounted on my Sig P365 AXG Legion with a Shield RMSc footprint, I found the sight to be slightly too long—about a millimeter off. This required me to carefully tap it into place using a rubber mallet. Fortunately, it seated securely without any damage, but this is something to be aware of for those with similar setups.A couple of minor drawbacks: the base is exposed, which feels like an odd design choice. While it sits flush with the firearm and likely won’t cause issues, a covered base to further protect the battery would have been preferable. Additionally, the detailed instructions are only available online, which is frustrating. A simple extra page in the packaging to explain key adjustments, such as the auto-on/off function, would have been a small but meaningful improvement.Despite these quirks, this dot remains an excellent sight at a competitive price point. It features a larger window than most micro red dots, making target acquisition easier, and it performs exceptionally well for those with astigmatism. With just a few small refinements, it could be near perfect.

I'm a huge fan of green dot sights and large windows on optics. I added this to my AR47 build and it has held up very well. It mounts securely to my rmr riser. Instillation is easy and plenty of screws are provided.

These are great for the price. I have one on my Canik Rival-S and it works great. I prefer green over red as it's clearer to me. Zero issues with background colors and is very bright in sunlight. Holds zero. No issues.
