The TRUGLO Fat Bead Universal Replacement Sight in green is a high-visibility front sight bead designed to upgrade or refresh shotgun fiber optic sights. Whether you're replacing a worn or damaged original bead or swapping to a brighter green fiber, this universal replacement accepts the standard 6-48 thread size found on most aftermarket and OEM shotgun sight bases. The fat bead's larger diameter gathers more light, making it easier to pick up in the field—especially useful in low-light hunting conditions or when shooting fast targets.
TRUGLO engineered this bead with precision: it's CNC-machined for consistency and durability, with a fiber core that's tough enough for hard use. The green fiber delivers excellent visibility across a range of lighting conditions, from early morning to overcast days. Because it's a universal design, the kit includes multiple mounting screw sizes, so you can dial in the right fit for your specific sight base without guessing or hunting for adapters.
Drop-in replacement sights like this one let you refresh an aging shotgun or customize your sight picture without a gunsmith visit. Keep one in your range bag or truck for emergency repairs at the range, or stock up if you run multiple shotguns.

Frequently Asked Questions
Will this replacement bead fit my shotgun sight?
If your sight base uses a standard 6-48 thread, yes. This is a universal replacement with multiple mounting screws to ensure compatibility with most common aftermarket and OEM shotgun sight bases.
What's the difference between this and a standard fiber optic bead?
The Fat Bead features a larger fiber diameter (0.100"), which captures more ambient light and creates a brighter, more visible sight picture, especially in challenging lighting or when following fast-moving targets.
What comes in the kit?
You get the CNC-machined green fiber bead and multiple mounting screws so you can fit it to your specific sight base.
Can I install this myself?
Yes. This is a drop-in replacement that unscrews from your existing sight base and screws on in minutes—no gunsmithing required.
