XS SIGHTSBig Dot Shotgun Front Sights with Tritium and Photoluminescent Glow Dot for Remington 870 and Mossberg 500/590, High-Contrast Sights for Plain Barrel Shotguns

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.

Was a little worried about using the JB Weld epoxy. It worked great! The XS Sight in orange on my 870 is a great fit. Looks factory. Very visible in dark and poor light. My white light would illuminate the original bead sight, but a white light is not needed in every case. This sight fills that void and then some!

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.

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.

I put this on my Remington 870 and its a game changer. I have better target acquisition. Its pretty simple to install.

Works just as it should, good daylight visibility and good glow from the tritium. You need to know what tritium is supposed to look like and understand the entire large dot doesn’t glow just a smaller center dot. I installed it on a Mossberg 590S with a factory bead sight. The XS sight won’t fit on the factory sight but a replacement bead sight is supplied that’s specifically for the XS. I test fit the sight on the new bead and taped around it very tightly then removed the sight and scuffed the area under the sight with a red scotch pad. Then used JB Weld (MIX THOROUGHLY) and used a tooth pick to make sure the hole the bead goes in is completely coated with epoxy. I clamped with a simple wood clamp with rubber feet (light pressure is all that’s needed) and cleaned up the excess JB with rubbing alcohol. Cleanliness is 100% critical installing this sight. Thoroughly clean the area EVERY STEP with rubbing alcohol for good results

If you follow the instructions and prep your surface (scuff and clean) you won’t have any trouble with adding this sight to your barrel. I heated the area after I set and clamped the sight in place, wiped excess with alcohol and came back the next day to see the JB weld expanded a small amount from heat and showed a little around the perimeter more than I intended. No biggy, but I advise to not heat the area so adhesive doesn’t slowly expand as it sets up. The other note I want to add is that my M500 barrel had a brass bead with a slightly smaller thread pitch / diameter than the bead included in the kit, and my existing bead was a little too large to fit inside the cavity of the sight base. Therefore I removed my existing sight bead and lightly put it in my drill press chuck and used a file and sandpaper to evenly reduce its size until it fit properly within the sight base. This is a great way to get around having to drill and tap your barrel for the included smaller sight bead. So far so good!

My eyes aren't what they used to be, and this is just the sight I needed! This is the 2nd one I've purchased. Works awesome in the day or night. This is a must have upgrade. You'll love it! Not complicated to install once you have the few materials you need. Nothing else out there that compares. This is the most visible front sight out there, bar none. Believe me, I've spent many hours searching and researching.

I ordered this for my Mossberg 500 Persuader 20", and I have to say I love it. I'm not as in love with the price, but you get what you pay for. Quality doesn't come cheap.I installed it using JB weld, the 24 hour set 2 part epoxy. Easy installation. pro tip: plan it out in advance, and take your time.The sight is large and in charge!! Easy to find quickly when shouldering the blunderbuss. Get one. I might get one for my other barrel. 🥰
