Keeping Traditions Alive Since 1953

Williams has been building rifle sights since 1926, and the Fire Sight line is one of the easiest upgrades you can make to a gun still wearing a plain factory front bead. This 290M model uses a red fiber optic rod that pulls in ambient light and focuses it into a bright, glowing dot. The more light it gathers, the brighter it glows, and it won't wash out even under strong sunlight. That translates to quicker target acquisition and a cleaner sight picture, especially in the low-light conditions where a standard black bead disappears.
The number and letter in the name tell you exactly what you're getting. The 290 refers to the .290" height, measured from the bottom of the dovetail to the top of the sight. The M means it uses the .340" medium-width base, which is the size made for factory ramps found on rifles like Marlin, Remington, and similar guns. If your rifle came with a Williams streamlined or shorty ramp, you'd want the narrower N series instead, so matching the width to your ramp is the key step before ordering.
This is a CNC-machined steel bead, not plastic, so it holds up to real use and knocks around in the field without complaint. Installation is a dovetail swap that replaces your existing front bead. Keep in mind that fitting a dovetail front sight almost always takes some minor filing or fitting to seat it snug and centered, which is completely normal for this style of sight. If you're comfortable drifting a dovetail with a punch and brass hammer, it's a straightforward afternoon job. If not, any gunsmith can set it in a few minutes.
The red front really comes alive when you run it against a contrasting rear. Williams offers matching Fire Sight rear units in green, and the red-front, green-rear combo gives your eye an unmistakable reference for lining up shots fast. On its own, the 290M is still a big step up from a worn factory bead for hunters and plinkers who want to see their sight in fading light.
The 290 is the sight height, .290" measured from the bottom of the dovetail to the top of the sight. The M indicates the .340" medium-width base, which is sized for factory ramps like those on Marlin and Remington rifles. Matching both the height and the base width to your rifle is the most important step before buying.
It's a dovetail swap that replaces your existing front bead, so no drilling or tapping is needed. That said, fitting a dovetailed front sight almost always requires some minor filing to seat it snug and centered. If you're handy with a brass punch and hammer you can do it yourself, otherwise a gunsmith can knock it out quickly.
The Fire Sight rod gathers ambient light and focuses it into a bright dot, so the more light it takes in, the brighter it glows. It's built not to wash out even in strong sunlight, which is where a plain black factory bead tends to disappear. You also get a usable sight picture as light fades toward the end of the day.
You can run it on its own as a big upgrade over a worn factory bead, but it really shines when paired with a contrasting rear. Williams offers matching Fire Sight rear units in green, and the red-front, green-rear setup gives your eye a fast, clear reference for lining up shots.
