Truglo
The Truglo Fat Bead Universal Replacement Sight with 5-40 thread size is a fiber optic front sight upgrade for shooters who want a brighter, more visible sight picture. Built on Truglo's proven fiber optic technology, this replacement bead is designed to fit a wide range of firearms where a universal mounting solution makes sense—whether you're upgrading an aging shotgun bead, swapping to a brighter red fiber on a rifle, or standardizing your sight setup across multiple platforms. The larger diameter bead catches and transmits more light than traditional brass beads, giving you a glow that stands out in the field without electronic power or batteries.
CNC-machined construction ensures precision and durability. The bead comes with a selection of mounting screws to match your specific mounting hole, so you're not hunting for hardware or forcing a misfit onto your gun. Red fiber is a proven choice for both hunting and range work—visible in most light conditions and fast to pick up on target.
Drop this in if you're working with a 5-40 thread receiver and want to refresh your front sight without replacing the entire assembly. It's a straightforward way to modernize older shotgun sights, add redundancy to a rifle setup, or give yourself more light gathering on a dim hunting shotgun.
| Thread Size | 5-40 |
| Fiber Diameter | 0.100" |
| Fiber Length | 0.5" |
| Fiber Color | Red |
| Construction | CNC-Machined |
| Mounting Type | Universal (multiple screws included) |
The Truglo Fat Bead is a universal front sight replacement compatible with 5-40 thread receivers. It comes with multiple mounting screws to accommodate different mounting holes, so it should work on most shotguns and rifles using that thread size—but verify your gun's receiver matches before ordering.
This is a fiber optic sight, meaning the red fiber transmits light to create a glowing bead that's easier to see against most backgrounds. The larger 0.100" diameter fiber gathers and displays more light than traditional solid brass, making it faster to acquire on target.
This is a replacement bead and mounting assembly with included screws. It's designed to swap into an existing 5-40 threaded mounting point on your receiver, not a full sight system.
Yes—many shooters install this as a redundant front sight or hunting sight on rifles as a backup to their optic, provided your receiver has a 5-40 thread available.
