## 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.
