Designed specifically for Mossberg plain barrel shotguns, these CNC-machined steel sights offer rugged durability and easy DIY installation. Made in the USA, they provide a snag-free, high-contrast aiming solution trusted by professionals for home defense and tactical use. ## Description Product description Our Big Dots measure 0.188” (4.8 mm) wide, making them the biggest front sight on the market. Our Original Big Dot Sights are equipped with self-illuminating tritium vials and a white convex dot. White helps overcome color vision issues, reflects ambient light, and stands out well on a long barrel. Our Second-Generation Big Dots are equipped with tritium and photoluminescent Glow Dot technology, which offers a high-contrast sight picture in bright light, absorbs ambient light, and glows in low light. Yellow glows the best, while Orange contrasts the best in bright light. The steel construction ensures the sights are protected from drops and will hold up for years. The steel surface is blued to resist rusting, with a regular cleaning and oil schedule. Our Big Dots have no sharp edges and will not get caught on clothing when attached to a system incorporating a sling. All XS night sights are CNC machined from steel bar stock in the great state of Texas for quality and durability you can trust. With over 20 years of night-sight manufacturing experience, the XS team has learned that defensive altercations don’t happen in perfect light or complete darkness. They happen in between these two broad spectrums. Night sights don’t just need to glow in the dark. They need to be visible at all times. Review: Perfect upgrade for Home Defense Shotgun, Easy installation and Great Results - Mossberg 500 - I decided to do some upgrades to my trusty old Mossberg 500 and one thing that always has been a struggle was finding a solid sight system for it. First I had an ATI heat shield with integrated ghost ring sights but they were made from polymer and mounted too far forward, kind of cheesy honestly. Then I attempted to modify a set of Tru Glos to work on this shotgun but sighting was impossible. So, this time around I was strongly considering the XS sighting systems Ghost ring rail with banded front night sight, which I would have loved to have but the $150 price tag had me on the fence for a 20 year old shotgun. But then it dawned on me, what good is a ghost ring paired with a night sight ? In a dark environment where your night sight would be imperative the black steel ghost ring would not be visible and possibly obscure your view of the front sight. So my best option I this case seemed to be this product. The price is right, installation was pretty straight forward and only took about 20 minutes not counting epoxy dry time and the result is excellent. The white big dot surrounding the tritium vial is very bright and easy to pick up and even as far away as the end of the barrel is the night sight is clearly visible in a dark room. A word of advice when installing , dry fit the sight and tape off around the perimeter. Use that as a grid to abrade the barrel finish only in the area needed, wipe thoroughly with alcohol before applying the epoxy, and the tip from another reviewer of using a zip tie to secure overnight was perfect. You Will Need to Purchase Epoxy for Installation, I ordered JB Weld along with the sight for another $4, worked great. I cant say 100% because I have only just installed it but as it stands now the sight is a great buy. Review: Great sight. Installation couldn't be easier. - While it is a little pricey, this sight works and looks great and is super easy to install. I mixed a little JB Weld, roughed up the original bead sight and stuck this one down. I used q tips to clean up the excess and that was it! The sight is much easier to pick up than the original bead and has the added benefit of the tritium for low light situations. Wish I would have purchased it sooner. ## Features - MOSSBERG KIT INCLUDES: Suits Mossberg plain barrel shotguns with beads between 0.120"-0.140"; Kit includes a conversion bead; NOTE: The hex base factory beads must be replaced and hole may need enlarging by gunsmith - DEFENSE-READY LOW-LIGHT PERFORMANCE: Our tritium sights are designed for optimal visibility, ensuring accurate aim in low-light conditions to enhance your defense capabilities; The orange dot excels in visibility during daylight conditions, ensuring you can aim accurately when it matters most - EASY DIY INSTALLATION: No need to be a professional to fit these tritium sights onto your shotgun; Our simple DIY instructions make it a breeze to install them yourself - MAXIMIZED TARGET ACQUISITION: Upgrade to our shotgun night sights for unparalleled visibility; Our state-of-the-art photoluminescent Glow Dot technology captures ambient light, glowing powerfully in low-light scenarios, which will ensure quick and precise aiming - MADE IN THE USA QUALITY: Our sights are CNC-machined from solid steel bar stock in our own in-house machine shop, ensuring you get the highest quality, American-made products ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RN29D6M | | Best Sellers Rank | #90,266 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #919 in Hunting & Shooting Optics | | Brand | XS SIGHTS | | Brand Name | XS SIGHTS | | Color | Tritium Orange Dot | | Compatible Devices | Shotgun | | Customer Reviews | 4.6 out of 5 stars 849 Reviews | | Global Trade Identification Number | 00647533046329 | | Included Components | Product | | Item Type Name | Holster | | Magnification Minimum | 1 x | | Manufacturer | XS SIGHTS | | Manufacturer Part Number | SG-2005-3N | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Name | FBA-BD-Shotgun | | Model Number | SG-2005-3N | | Mounting Type | Picatinny Mount | | Night vision | Yes | | Product Style | Mossberg 500/590 | | Reticle Type | Luminescent | | Sport | Shooting | | Sport Type | Shooting | | Style | Mossberg 500/590 | | UPC | 647533046329 | | Warranty Description | 2 Year Manufacturer | ## Product Details - **Brand:** XS SIGHTS - **Color:** Tritium Orange Dot - **Compatible Devices:** Shotgun - **Magnification Minimum:** 1 x - **Material:** Alloy Steel - **Model Name:** FBA-BD-Shotgun - **Mounting Type:** Picatinny Mount - **Night vision:** Yes - **Sport:** Shooting - **Style:** Mossberg 500/590 ## Images ![Big Dot Shotgun Front Sights with Tritium and Photoluminescent Glow Dot, High-Contrast Sights for Plain Barrel Shotguns - Image 1](https://m.media-amazon.com/images/I/61VVold2xGL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect upgrade for Home Defense Shotgun, Easy installation and Great Results - Mossberg 500 *by J***N on October 15, 2016* I decided to do some upgrades to my trusty old Mossberg 500 and one thing that always has been a struggle was finding a solid sight system for it.

Installation couldn't be easier. *by B***L on April 13, 2024* While it is a little pricey, this sight works and looks great and is super easy to install. I mixed a little JB Weld, roughed up the original bead sight and stuck this one down. I used q tips to clean up the excess and that was it! The sight is much easier to pick up than the original bead and has the added benefit of the tritium for low light situations. Wish I would have purchased it sooner. ### ⭐⭐⭐⭐⭐ Wonderful *by J***S on September 18, 2022* Easy to install with some JB weld, looks great, glows bright, and looks factory once installed. I want to write a longer review but the honest truth is, this was the best investment I have put on my shotgun in a long time. I am not gonna lie and say its cheap (I am pretty stingy), but it is worth the cost. Honestly I love how bright the yellow is in low light, and with the tritium dot it is easy to find a reference point in the dark, and the glow-ring feature is nice. Really love this sight, and if you are on the fence, this is a great sight for home defense. If you are looking for one for Hunting or Sporting Clays though I would not recommend this sight (go look at the hi-viz fiberoptic sights if you need a brighter sight for those needs), but that's not why I bought it, and I doubt that's what brought you to this product in the first place. ## Frequently Bought Together - XS SIGHTS Big Dot Shotgun Front Sights with Tritium and Photoluminescent Glow Dot for Remington 870 and Mossberg 500/590, High-Contrast Sights for Plain Barrel Shotguns - J-B Weld 8265S Original Cold-Weld Steel Reinforced Epoxy - 2 oz. - J-B Weld 8276 KwikWeld Quick Setting Steel Reinforced Epoxy - Dark Grey 2 oz --- ## 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.hr/products/170946071-big-dot-shotgun-front-sights-with-tritium-and-photoluminescent-glow](https://www.desertcart.hr/products/170946071-big-dot-shotgun-front-sights-with-tritium-and-photoluminescent-glow) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-23*
