Description

What is the footprint of this red dot? This Nautilus features a K-series 407K/507K footprint. How do I know if I have an Shield RMSc or K-Series 407K/507K footprint? The primary difference between the two is that the RMSc features 4 recoil lugs while the 407K/507K uses only two which is why all RMSc red dots fits on K-series but not the other way around. Which model work straight out of the box with no mods/plates? Bul Armory SAS II Ultralight, SW M&P 5.7, Equalizer, Sig P322, 365X/XL/X‑Macro/365‑380, Canik TP9 Elite SC, Mossberg 940 Tactical, Taurus TX22 Compact, GX4, GX4 XL T.O.R.O, Ruger Max‑9, Shadow Systems CR920, PSA 5.7 Rock, PSA Micro Dagger What do I need to get this to work with my current RMSc setup? You'll only need an adapter plate for get this working. What is the size of the dot? This model features a 3 MOA dot.

    • Good option for range toys
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. ... show more

    • Cheap in price, not in quality!
I've had this for a few months now and ran close to 400 rounds and it still holds zero. Easy to mount and easy to adjust. I recommend this sight for anyone looking to not break the bank. The dot gets plenty bright and has great visibility outdoors where I do all of my shooting. Buy one and give it a go, you won't be disappointed. ... show more

    • Tristan sight
I was looking for a sight that would fit my Dpp sight plate on my Taurus g 2c 9mm. It fits perfectly. I went and shot a hundred rounds with it, had no problem. Its about time to find something at a good price that works this damm good. I will buy one for my 380. I do say if you're looking for a red dot this is the right one for the right foot print and price. It looks really good on my gun. Very satisfied. ... show more

    • Good Item, Not Great listing.
Purchased to use on a Galloway Precision optics plate for a Ruger LC9 which supports 407/507K footprint optics but screw holes were off by a bit more than would fit. Ended up returning and replacing with an ADE green dot that fit. But, if this fits your pistol it does look like it could be a great value dot. I just wish it would have worked for me. ... show more

    • Overall Experience
Holds a zero, used on a tx22. Be aware the blue loctite from factory doesn't go all the way to the bottom, you might want to purchase some before hand to put a drop on the tip of screws. I learned the hard way and overtightened a screw, which later rounded out during removal. Had to use a Dremel to create a flathead notch. Fortunately the optic comes with spare hardware. Good quality optic, seems like cheap screws. Also shake awake doesn't seem to function. Once I reinstall, I'll update after a deep clean and blue loctite. 2k rounds already on it so far. ... show more

    • I’m not sure what to think…..
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. ... show more
