XS SIGHTS Big Dot Shotgun Front Sights with Tritium and Photoluminescent Glow Dot, High-Contrast Sights for Plain Barrel Shotguns

If you are going to go with a bead sight, this is the one to have. Easy to install, it’s bright and target acquisition is spot on. If I purchase any more bead sighted shotguns, this will be my go to always.

Very bright and worth the price!

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.

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.

Pros: It glows about the same intensity as pistol sights. It’s bigger than most factory beads Has white and black inset for changing environments. Cons: Make sure you are willing to be patient to set correctly You will need a few other tools around to install. Irreversible once set You will need: JB Weld mix, Clamps or a vice, alcohol, a cotton cloth, q tips to clean up the bond mix once you’ve set the sight, needle nose pliers for the inset metal bead Review: I have a Mossberg 930 that came with a cylinder-like bead sight from the gun merchant. It was very low to the barrel and I would always shoot too high on the target. I didn’t want to spend 250+ on a sight like a Holosun due to the maintenance of such scopes. Also, I’m not a hired assassin, so I don’t need to spend too much on a gun. It has a job it will probably never be called upon to do. I just wanted something simple that gave me a similar feel to my sights on my pistol in the dark. The setup was easy but I made sure I checked sight alignment while using clamps to set the sight correctly. It fits solid and I see so much clearer with the sight. Low maintenance and the bead aligns in a “second nature” position once I pull from the ready position. Hopefully I will never have to use this system for it’s designed purpose. But I feel much better with this sight than anything with batteries, or that’s much smaller, or that might have electrical malfunctions.

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.

They are brighter at low light and pickup faster sow they are worth buying .

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

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. 🥰

Extremely well made. Easy installation. There is a great youtube tutorial. Glows bright. Easy target acquisition. It raises the sight over a heat shield as well. I have one on two of my 590s. Its a must for any home defence or wildlife defence shotgun.
