Description

Trading the factory buckhorn for a receiver peep is one of the best things you can do for a lever action, and the Williams FP-94/36 Foolproof is a classic for good reason. It mounts on the side of the receiver using the two drilled and tapped holes many Winchester and Marlin rifles already have, putting the aperture close to your eye where it belongs. That longer sight radius and simple peep-and-bead picture make target acquisition faster and shots more repeatable than an open notch ever could.

How the FP-94/36 Foolproof Holds Its Zero

The heart of this sight is the internal micrometer system. Windage and elevation adjust with positive internal locks, so once you dial it in, recoil and rough handling in the truck or the deer stand won't walk your point of impact around. It's built from aluminum alloy with a tensile strength of 85,000 pounds and uses steel mounting screws, so you get a tough sight that still tips the scale at only about 1-1/2 ounces. The blued-black finish looks right at home on a traditional lever gun.

Fitment for the Williams FP-94/36 Receiver Sight

This model covers a wide swath of popular guns. It fits the Winchester 94 Top Eject, plus the 55, 63, 64, 65 and 9422, along with side-drilled Marlin 36, 336, 444, 44 Mag, 93, 1894, 1895 and pre-2001 1895G, and Sears centerfire lever actions. Older rifles that were never drilled and tapped on the left receiver wall may need that done first, so it's worth checking your gun before ordering. Because the FP-94/36 sits low over the receiver, most folks find they can keep the factory front bead, though some prefer swapping to a taller blade depending on their load and eyes.

Pairing the FP-94/36 with a Twilight Aperture

The threaded aperture makes it easy to fine-tune your sight picture. A lot of hunters step up to a Williams twilight disk with its brass ring, which pairs beautifully with a brass front bead and speeds up sight acquisition in low light. A smaller opening helps sharpen the front sight for aging eyes, while a larger disk works well for deliberate target shooting.

Frequently Asked Questions

What rifles does the Williams FP-94/36 fit?

It's designed for the Winchester 94 Top Eject and models 55, 63, 64, 65 and 9422, plus side-drilled Marlin 36, 336, 444, 44 Mag, 93, 1894, 1895 and pre-2001 1895G, along with Sears centerfire lever actions. The receiver drill-and-tap spacing is shared between the Winchester 94 and Marlin 336, which is why one sight covers both families. Just confirm your specific rifle has the peep-sight holes on the side of the receiver before mounting.

Do I need to drill and tap my receiver for the FP-94/36?

Many Winchester and Marlin lever guns left the factory already drilled and tapped on the side of the receiver for a sight like this. If yours has those holes, installation is a straightforward bolt-on job with the included screws. Older rifles that were never drilled and tapped on the left receiver wall will need a gunsmith to do that first.

Will I need a taller front sight with the FP-94/36 Foolproof?

Usually not. This sight sits fairly low over the receiver, so most shooters can keep their factory front bead and still zero without trouble. If your particular load or eyesight has you running out of elevation adjustment, swapping in a slightly taller front blade solves it, and plenty of folks change to a blade anyway simply because they prefer it over a bead.

How do the adjustments work on the Williams FP-94/36?

The FP-94/36 uses internal micrometer adjustments for both windage and elevation with positive internal locks. You dial your corrections a click at a time, and once locked in, the zero stays put through recoil and everyday handling. The aperture also threads in and out, so you can swap to a different peep or a twilight disk to tune your sight picture.
