Big Dot and Standard Dot Night Sights are defensive tritium sights designed to enhance your defense gun. The sights use a proprietary photoluminescent Glow Dot that absorbs ambient light and glows in low light. The convex dot's additional surface area increases light absorption, intensifying the charge of the Glow Dot. Designed to be large and highly visible, these sights help solve many issues, from aging eyes to deteriorating vision. We've found that the orange front tends to be most visible in daylight settings and that yellow glows brighter in low light, while green is an excellent option for low light and has a very bright glow intensity. XS Tritium Night sights are big, bright, and easy to see day or night!
The sights are CNC machined from solid steel bar stock by our in-house machine shop. We design, machine, and insert our tritium to produce the highest quality possible and provide American Made products. We are a small, second-generation family-owned business based in Fort Worth, TX, and our customers are family.
We live, eat, and breathe guns. We offer easy DIY instructions, a 30-Day Satisfaction Guarantee, and stand behind a 10-Year No Questions Asked Warranty on all our sights. If you break your sight training, we want to hear about it. If you damage your sight installing it, give us a call, and we will get a new one mailed out after a friendly lecture from one of our gunsmiths. If you have color vision issues and can't see the front dot, call us, and we will get another color shipped out. (Over 5% of the population has color blindness to a degree!) Either way, our products are built to take a beating, and we have your back if anything happens.

Glues over front bead. Bead must be 0.120”-0.140” in diameter. Suggest Brownells #6 or #26 bead if factory is not of correct size. May require opening up bead hole to larger size by drilling & tapping. Mossberg factory bead with hex base must be replaced. The kit comes with a conversion bead for Mossberg shotguns.

If your shotgun came with a simple brass bead sight, this is one of the best upgrades you can make to your shotgun, imo. Much larger and highly visible both day and night in a variety of conditions. Easy installation. Just do it.
Mossberg big dor
I ordered the white big dot front sight for the mossberg 500. It cowitness’s nicely with the aridus crom holosun mount that uses an xs rear sight. Great product easy to install.
Easy install. Fantastic sight picture. Third shotgun to get an XS sight. So much better than factory beads.
Fantastic upgrades in visibility, accuracy, and precision to your shotgun
My Mossbergs came with a bead sight that was barely visible in the daytime, and certainly not usable in the nighttime, even with a mounted flashlight. I have had previous experience using a Fiber Optic snap on sight, but it was noticeably less durable than a built in fixed option. After a lot of research, everyone pointed me to XS Sights. Instructions and videos are all available, and installation was easy. The dot is basically bombproof when installed with JB weld. I've tried both the Tritium and Non-Tritium version, and I personally like the Tritium for dusk/dawn/twilight environments, but it's not a requirement, the basic big dot is usable as well. It draws your eye in quite well and helps in getting a good consistent cheek weld. This would be my recommendation if you don't want to install a rail+rear and front sight on your shotgun (XS makes that option as well).
