The Williams Gun Sight Marlin 2-Dot Fiber Optic Dovetail Rear Fire Sight in green is a rugged, reliable upgrade for Marlin lever-action rifles. If you've been shooting factory sights and want faster, more positive target acquisition—especially in low light or brush—fiber optic sights make a genuine difference. This rear sight uses a U-notch design with two green fiber optic dots that gather light and stand out clearly against your target, cutting the time it takes to settle on your aim. It's built to replace your Marlin's factory rear sight and fits via dovetail, the same proven mounting method used on quality rifles for over a century.
Setup is straightforward: the rear sight is screw-adjustable for elevation and drift-adjustable for windage, so you can dial it in at the range without gunsmithing. Because it dovetails directly into your rifle's existing dovetail slot, you won't need any special tools or permanent modifications. Minor fitting may be required depending on your individual rifle, but that's normal with dovetail sights and usually takes a few minutes with a sight pusher or a careful hand.
Williams Gun Sight has been making iron sights since 1932, and their fiber optic line carries that legacy forward. The green fiber gathers ambient light and reflects it straight into your eye, which means the sight actually becomes more visible when you need it most—dawn, dusk, or overcast days when traditional notch sights fade. It's the same advantage that's kept shooters reaching for fiber optic sights on hunting rifles, 3-gun guns, and anything that needs to be quick and reliable in the field.

Yes. The rear sight features screw-adjustable elevation and drift-adjustable windage, so you can dial it in to your point of impact at the range without needing a gunsmith.
