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

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.

I was a bit unsure when I ordered this sight, but after watching videos on youtube on how to install it, I could do a good job mounting it. I removed the factory bead and replaced it with the provided one in the XS Sight package. The only drawback is that it didn't come with the adhesive needed to bond it to the barrel. The sight itself is glued on and not screwed in. I bought J-B Weld 5,000 PSI to cement the sight. After properly affixing it, I used a small clamp to keep it in place while it dried up. After 12 hrs, it was perfectly attached. The product is well-built and sits perfectly well on my shotgun. It looks and feels like it came factory installed. The sight provides a clear and bright view in all lighting conditions. This shotgun sight, is one of the best options out there.

After considering some kind of sighting improvement for my home defense Mossberg 590A1 I settled on the XS Big Dot sight. I've had this sight installed for a few months now, but have been waiting to write a review until after I got to put it through its paces at least a little bit.I have tried plain beads and an RMR before, but this is my favorite setup. It is the best of both worlds: the speed and simplicity of a bead with the easy visibility and low light capability of the red dot (at a fraction of the price). It has survived the normal bumps and scrapes as well as a full day tactical shotgun course. The small white lettering on the sight is all gone now, but the sight itself remains otherwise unscathed. Install was simple. When replacing your bead make sure the new bead fits properly in your barrel before installing it with a thread locker. As one reviewer pointed out, be sure to remove finish from bottom of sight and portion of barrel sight will affix to and make sure it is all clean and dry and free of any grease to help ensure a good metal-on-metal bond.
