TRUGLO Fat Bead Universal Front Fiber-Optic Sight

The TRUGLO Fat Bead Universal front fiber-optic sight is a CNC-machined, large-diameter bead replacement engineered for high visibility and rapid sight acquisition in varied lighting. The sight uses a light-gathering fiber available in single- and dual-color options (single color fiber diameter .100", dual color .120") with a fiber length of 0.50". Universal mounting hardware is included—different size mounting screws and thread adapters (6-48 / 3-56 / 2.6mm / 5-40 / 3mm)—to accommodate common thread sizes; compatible listings also note Picatinny and Weaver mounting compatibility. Matte finish black housing and durable metal construction provide a low-profile, robust replacement sight. Endorsed by Ducks Unlimited; may require gunsmith installation for some fits.
