Williams FireSights Fiber Optic Set (Marlin 336/1894/1895)

Not every Marlin owner wants a ghost-ring conversion or a rail full of glass. For the shooter who likes the factory open-sight handling but wants a faster, brighter sight picture, Williams FireSights are the obvious first buy. The set replaces the factory front and rear with fiber-optic equivalents: a green rear and a red front that glow in available light and pull your eye to the front bead far quicker than a plain black blade in timber or at dusk.

Williams has built sights for over ninety years, and these are a true drop-in for the Marlin 336, 1894, and 1895 dovetails, no drilling, tapping, or gunsmithing. The rear is windage and elevation adjustable, and the high-contrast color pairing makes lining up the irons nearly instinctive under field conditions where the factory sights wash out.

At well under sixty dollars, this is the highest value-per-dollar sighting upgrade on the rifle. It will not give you the precision of an aperture or the reach of an optic, but for fast, close work in poor light, the contrast gain is immediate.
