Marble Arms 3/32in Shank Fiber Optic Bead Sight, 3-56 Thread, Green

The Marble Arms 3/32in Shank Fiber Optic Bead Sight, 3-56 Thread, Green is a replacement front sight bead from Marble Arms (brand part no. 035615), a fiber optic bead front sight insert in green. Marble Arms beads thread directly into a barrel’s existing front sight base, letting shooters swap sight-picture styles or replace a worn or damaged bead without buying a whole new front sight. This bead gathers ambient light so the green bead glows for a fast sight picture. It is sold as an individual replacement bead, not a complete sight assembly.

Key Specifications

• 3/32-inch shank diameter matches the standard bead-sight mounting hole on most barrels.
• 3-56 threaded stud matches the mounting thread size for a correct, factory-pattern fit.
• Green bead gathers ambient light so the green bead glows for a fast sight picture.
• Fiber optic construction channels light through a fiber rod rather than relying on paint or coating.
