Nautilus 3 MOA | 407K, 507K Footprint | Modified RMSc, NO Rear Recoil Lugs, NOT RMS Compatible | Parallax-Free Micro Red Dot Sight (MRDS) Featuring Shake Awake and 50K Hour Battery Life

Works great has good brightness, but unfortunately when I was using it today after two magazines or 30 rounds, it’s shut off and wouldn’t turn on even if I pressed the button on that that’s when I switched to my iron sites and after a few rounds, started to work again, but kept on shutting off randomly packaging is really good comes. There’s a lot of good hardware seems really good for the price. It’s most likely I just got unlucky,

It's held zero on a TX22 with FRT for 3-4 thousand rounds so far. When i forget and leave the brightness turned all the way up I sometimes have to change the battery the next time I go to the range. The shake awake is probably just slightly too sensitive but for the money I won't complain. Specially holding zero on a pistol that can exceed 1600 rounds per minute. I just bought a cheap pack with a bunch of batteries so that also could play a role in batteries dying fast. Also nice that you can switch batteries in under a minute without removing the optic like on some other low cost options. I prefer 32 moa but It's got a nice size dot that's easy to put on target. It's not the best dot optic I own and I probably wouldn't trust my life with it but it's worth it for a range toy. So far no real problems. Will update if anything changes.

Excellent. Low profile, excellent quality and material. Packaging was excellent. Sighted in beautifully. Looks great installed. And that price, muah, love it. Will be purchasing another one in the future. I only wish the made it with a green dot. We will see how the battery life goes. But it’s been great so far!

Not sure about this one. When it arrived I mounted it on a Taurus GX4 and headed to the range. Sight in was easy enough and everything worked as it should. Took it out today, along with a few others for a little practice. The dot was very dim, almost not visible but when I pressed the + it dimmed further and then turned off. I pressed both buttons but nothing happened. I figured it was the battery and though it shouldn't be dead, it happens. When I got home I replaced the battery and pressed the + button and nothing happened. But when I pushed the - button the sight came on but very dim. If I pressed the - button it got brighter. If I pressed the + it dimmed. The opposite of what should happen. Anyway, heading back to the range tomorrow, let's see what happens.

Mounted good. Feels solid. 3rd time to the range and it’s dead. Maybe 300-400 rounds thru it. In the middle of shooting today the red dot would turn on and off with shots. Shake the gun and you could watch the dot flicker. DO NOT GET THIS DOT! Spend more money and get a better optic. Out of window to send back. If the seller wants to warranty this I will update accordingly. ******update****** No contact from seller…. Was going to take this off and got too looking it over. Couldn’t find anything lose. No noises when I shook it. Took the original battery out and put a new one in that I know is good. Took it to the range today and put 200 rounds thru it without a single complication. I just needed to put rounds thru it wasn’t really worried about accuracy lol. Maybe it was just the battery? This isn’t my main toy, just one I picked up to add into my rotation. It’s mounted to a CDS9. Mounts up just fine. Looks decent. I don’t think I’d trust my life on this optic but it may be good to break them in with. I’ll put some more rounds thru it and update. Another Update….. Made contact with seller. They shipped me out a new dot. Had it on the firearm for a couple months and put around 500 rounds or so thru it with no issues. Went to the range yesterday and 1/2 way thru it shut off. Messed with the battery cover and couldn’t get it to come back on. Got home and it was operating again. Not sure what’s going on but this is 2 with the same issues.

I like the sight, works well with good features, but the description says it will fit the Ruger max 9 but doesn’t , I bought two and used one on a Taurus tx22 compact and it fits perfect I’ll use the other one on something

Absolutely great product for the price. As soon as I open the box, I could see that it was made out of quality material and it mounted perfectly to my Smith & Wesson m&p5.7. The installation was easy and with the multiple levels of brightness it’s great for any situation.

Accurate and adjustable to my needs
