There’s a lot of good hardware seems really good for the price. It’s most likely I just got unlucky, Review: 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. ## Features - Footprint Options: Available in both RMR and 407K, 507K footprints for compatibility with a wide range of pistols.

Worth every penny. *by B***S on February 18, 2026* 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! ## Frequently Bought Together - Triton 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 - Feyachi Bore Sight 9mm/12 Gauge/223 5.56mm Red/Green Laser Zeroing Boresighter with 3 Sets of Batteries - Monstrum Dovetail Red Dot Mounting Plate for Glock Pistols | for Non-MOS Version Glocks | Compatible with Glock 17 19 20 21 22 23 34 35 40 41 45 47 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/700743101-nautilus-3-moa-407k-507k-footprint-modified-rmsc-no-rear](https://www.desertcart.co.za/products/700743101-nautilus-3-moa-407k-507k-footprint-modified-rmsc-no-rear) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
