Standard Bradley Front Sight Beads – 1/8" 6-48 TPI, 5/64" Shank
This model, 146186032, is specifically the Standard Bradley Style Bead packaged as a 3-pack:
Bead size: 1/8" standard front bead
Thread: 6-48 TPI – one of the most common front sight thread sizes on many American-made shotguns
Shank length: 5/64" shank for typical shotgun rib and barrel thicknesses
Color: White – high contrast for fast target acquisition
Quantity: 3 beads per pack
These beads are listed as fitting “Universal Shotguns” with the proper thread size, making them ideal as replacements or upgrades on many pump, semi-auto, and break-action barrels that use 6-48 front sight threads.
“Bead-on-a-Block” Bradley Design – Strong, Straight, and Secure
Bradley Gunsight beads are known for their unique “Bead-on-a-Block” construction. Instead of a bare bead on a thin stem, the bead is mounted on a small steel block that sits flush on the barrel:
The steel block provides positive indexing, helping keep the bead straight and properly aligned.
Extra surface area at the base increases strength and resistance to loosening or bending.
This design offers greater durability under recoil and hard field use compared to simple screw-in beads.
According to Bradley’s own safety sheet, this original “Bead-On-A-Block” design was created to give shooters greater surface area and increased strength at the front sight, making it a preferred choice for serious hunting and working guns.
Bright White Beads for Fast Target Acquisition
These SIGHT BEADS 146186032 are white standard Bradley beads, chosen for maximum visibility:
High-contrast white bead stands out clearly against dark timber, brush, and moving birds.
Makes it easier for your eye to pick up the muzzle instantly when you mount the gun.
Ideal for waterfowl, upland birds, turkeys, doves, and clay targets where fast sight alignment matters.
Many shooters prefer a plain white bead over fiber optics or glowing sights because it offers a clean, distraction-free aiming reference that works in almost all lighting conditions without glare or bloom.
Universal 6-48 TPI Compatibility – Great for U.S.-Made Shotguns
With its 6-48 TPI threads, the 146186032 bead targets one of the most common front sight thread sizes seen on U.S.-pattern shotguns:
Fits barrels and ribs tapped 1/8" 6-48 at the muzzle.
Suitable for many popular pump, semi-auto, and single/double-barrel shotguns that use this thread standard.
Labeled as “Universal Shotguns” – Standard Bradley Style Beads, indicating broad compatibility where the thread size matches.
As always, it’s smart to verify your barrel’s existing front sight thread or consult a gunsmith before ordering, but for 6-48 threaded muzzles this bead is a direct, no-adapter solution.
3-Pack Value – Perfect for Gunsmiths, Builders & Multi-Gun Owners
Each package of SIGHT BEADS 146186032 includes three matching front beads, which is ideal for:
Gunsmiths and armorers doing multiple shotgun builds or repairs.
Shooters who own several shotguns and want the same sight picture across their lineup.
Keeping spares in the toolbox in case a bead is damaged, lost, or swapped during customization.
Instead of buying single beads repeatedly, a 3-pack gives you better value and flexibility for current and future projects.
Ideal Uses – Hunting, Clays, and Workhorse Shotguns
The Bradley Standard Bead 146186032 is a smart upgrade or replacement for:
Field shotguns used for ducks, geese, doves, pheasants, quail, and other game birds.
Clay target guns used for trap, skeet, and sporting clays, where a crisp front reference is important for consistent leads.
Farm and working shotguns that need a robust, easy-to-see front sight that won’t bend or shear off easily.
Whether you’re restoring an older barrel, replacing a missing bead, or standardizing the sight picture on your shotguns, this Bradley bead offers rugged reliability and clean visibility.
Durable Construction – Steel Base, Proven Materials
According to Bradley’s documentation, their Standard beads are built with a steel base and beads available in colored plastic or brass options, with the 146186032 version using a white bead.
Steel block base for superior mechanical strength and secure mounting.
Designed to withstand recoil, repeated cleaning, and harsh field conditions.
Maintains alignment and integrity far better than thin-stemmed front beads.
Install it once and, with normal maintenance and cleaning, you can rely on this bead for many seasons.
