Truglo Fat Bead Universal Replacement Sight 2.6mm Thread, Green

The Truglo Fat Bead Universal Replacement Sight with 2.6mm thread is a straightforward upgrade for shooters who want a brighter, more visible front sight on shotguns and other firearms that use this standard thread size. Built around Truglo's proven fiber optic technology, the green bead gathers ambient light and glows without batteries, making it easier to acquire your target in low-light conditions—dawn, dusk, or heavy cover—than a traditional brass bead. If your gun's front sight has taken a beating or you're simply tired of squinting at a dull bead, this is a practical, affordable swap.

Installation is simple: unscrew your old bead, thread on the Fat Bead, and you're done. The fat profile gives you a larger, more forgiving sight picture than a standard bead, which is especially useful when you're moving fast or shooting in challenging conditions. Truglo has built a reputation for tough, reliable fiber optic sights that hold up to the recoil of shotguns and rifles alike, and this replacement maintains that standard.

This is not a tactical upgrade or a precision instrument—it's honest, dependable iron-sight technology for hunters and shooters who value simplicity and visibility. Whether you're running a pump action, semi-auto, or inertia-driven shotgun with a 2.6mm thread, this replacement bead will outlast the gun if you treat it right.

Frequently Asked Questions

Will this fit my shotgun?

If your shotgun's front sight accepts a 2.6mm thread, yes. This is the standard thread size for many Beretta, Benelli, and Stoeger shotguns, among others. Check your gun's manual or measure the existing bead's thread size to confirm.

Do I need tools to install it?

No. You simply unscrew the old bead by hand and thread on the Fat Bead. If it's very tight, a rubber grip or cloth can help, but no special tools are required.

How does fiber optic sighting work?

The green fiber optic material collects and concentrates ambient light, making the bead appear to glow without batteries. This makes it faster and easier to see and aim at than a standard brass or steel bead, especially in dim conditions.

Is this better than my current brass bead?

The fiber optic design is more visible in most lighting situations, so if you're hunting in early morning, late afternoon, or overcast conditions, you'll likely notice a difference. In bright daylight, the advantage is smaller, but the bead will still be easier to see.
