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.

## Questions & Answers

**Q: some images uploaded of the big dot seemingly have the tritium glowing in indoor light. mine is not nearly this bright. did i get a dud?**
A: No, I don’t think so - all my tritium sights (XS Big Dot on my Shockwave and several others on various handguns) only “glow” in low light or the dark. In daylight I focus on the large white outline of the XS sight.

**Q: will this work on a 1300 defender?**
A: Actually, yes. However, you must first replace the factory bead on your Winchester. A Brownell's #6 will work great. There will be excess material on the inside of the barrel, but this is easily ground off with a roto tool.

**Q: Does this work on the sight with bead on the pedestal**
A: For proper fit & install, original bead has to removed & replaced w/new bead provided from XS Sight.  If you have pedestal, has to be wide enough to accommodate width of XS Sight.  Unfortunately, most pedestals are narrow & XS Sight has a wide base.

**Q: Not understanding pedestal or plain barrel option. i have a bead with a hex base. please explain?**
A: Is your bead on a pedestal, like Remington 870s, or is the bead installed directly onto a plain, round barrel. If your shotgun is a Mossberg and has a small bead with a hex base drilled directly into the barrel, then you want the plain barrel. The XS kit comes with a replacement bead for this model since the steel sight will not fit over the hex base and Mossberg uses proprietary threading. If you have some other shotgun with a bead with a hex base, but it's on a plain barrel, you'll want to plain barrel model, but will also need to source a replacement bead with the threading the manufacturer used.

### ⭐⭐⭐⭐⭐ 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.
