Frequently Asked Questions
Which shotguns are compatible with the 5-40 thread bead?
The 5-40 thread size is one of the most common bead thread specifications and fits a wide variety of popular shotguns, including many Mossberg, Remington, and Winchester models. Before purchasing, verify your current bead's thread specification by removing it and checking with a thread gauge or consulting your firearm's manual. When in doubt, a qualified gunsmith can confirm compatibility in minutes.
Does the tritium bead glow during the daytime as well?
Tritium is continuously self-luminous, meaning it glows around the clock — but the glow is most visible in low-light or no-light conditions. In bright daylight, the bead functions as a standard front sight and the tritium element may not be prominently visible. Its true advantage emerges at dusk, indoors, or in darkness where a conventional bead becomes nearly invisible.
How difficult is it to install the Meprolight TD Shotgun Bead?
Installation is straightforward for most users comfortable with basic firearm maintenance. Simply unscrew your existing front bead using the appropriate tool (often a small screwdriver or bead wrench) and thread the Meprolight TD Bead into the same hole. Because tritium vials are sealed inside the bead housing, no special handling is required. If you are unfamiliar with the process, a local gunsmith can complete the swap quickly and inexpensively.
