Keeping Traditions Alive Since 1953

Marble Arms has been making front sights since 1900, and the 45W carries that same reputation into the fiber optic era. This is a barrel-mounted sight standing .450" tall measured from the top of the bead to the bottom of the dovetail, with a .531" wide base sized for a standard 3/8" dovetail cut. The green .060" fiber optic rod gathers ambient light and glows, giving you a clear reference point that beats a plain bead when you're working in shade, at dawn, or against a busy background.
This one is built for lever guns and traditional rifles that came factory equipped with a dovetail front sight. The .450" height is on the taller side of the lineup, which makes it a smart pick if you're pairing it with a peep or rear sight and need to raise your point of impact. Green fiber tends to read fastest for most eyes in normal daylight, and it pops against dark game or timber where an old brass bead can disappear.
The whole sight is machined from steel, so it holds up to recoil and years of field carry without the fragility you get from cheaper cast parts. Like most Marble sights, the base runs a touch oversized on purpose. That means a few passes with a fine triangle or slim taper file to fit it snug into your dovetail, which is exactly what you want for a rock-solid, no-wiggle install. Once it's seated, the sight is drift adjustable for windage by tapping it left or right in the dovetail.
If your original front sight is worn, cracked, or just hard to pick up with aging eyes, swapping in the green 45W is one of the simplest upgrades you can make to an iron-sighted rifle. It looks right at home on a classic gun and gives you a modern sight picture without changing the character of the rifle.
It's cut for a standard 3/8" dovetail with a .531" wide base, which is what most lever guns and traditional rifles use. Marble builds the base slightly oversized so you can file it for a tight, custom fit. Plan on a few passes with a fine file before it seats fully.
The 45W measures .450" from the top of the bead to the bottom of the dovetail, putting it toward the taller end of Marble's fiber optic lineup. Front sight height controls your point of impact, so a taller sight lowers where the rifle prints and a shorter one raises it. If you're shooting high or running a peep sight, the added height helps bring your groups down onto target.
It comes down to your eyes and your background. Green reads fast for most people in normal daylight and stands out well against dark timber or game, while orange can pop harder against green foliage and snow. Both use the same .060" rod, so it's really a personal preference call.
Yes. Once it's fit into the dovetail, the 45W is drift adjustable, meaning you tap it left or right in the slot to move your point of impact for windage. A brass punch or dedicated sight pusher makes the job easy without marring the steel.
