Frequently Asked Questions
Why choose yellow tritium over orange or white for the Remington 870?
XS Sights offers multiple tritium color options for good reason — yellow tritium glows the brightest in low-light and nighttime environments, making it the top choice for home defense scenarios where lighting is minimal. Orange tends to perform best in daylight for fast acquisition, while white is non-glowing but highly reflective across various lighting situations. If your primary concern is visibility in darkness, yellow is the recommended option.
How long does the tritium illumination last on XS Big Dot sights?
Tritium is a naturally occurring radioactive isotope that gradually decreases in brightness over time. XS Sights tritium vials are rated for approximately 12 years of self-luminous glow, after which the sight will still function as a standard bead but will no longer self-illuminate in the dark. The photoluminescent Glow Dot will continue to work as long as it is charged by ambient or UV light.
Does this sight require professional installation on the Remington 870?
The XS Big Dot sight is designed to fit the Remington 870 platform specifically, and many experienced shooters are able to install it at home with basic gunsmithing tools. However, if you are not comfortable with sight installation or want to ensure proper alignment and torque, having it installed by a qualified gunsmith is always a good idea.
