Why a peep beats a buckhorn
Most lever guns leave the factory with a bead or post up front and a buckhorn or semi-buckhorn notch out on the barrel. Marlin's Classic Series lists adjustable semi-buckhorn sights. Henry's big-bore manual describes a fully adjustable semi-buckhorn with a white diamond insert. They are traditional and they work, but they ask your eye to juggle three things at different distances: rear notch, front sight and target.
An aperture, or peep, sight fixes that. You look through a small hole close to your eye, and your eye centers the front sight in it on its own. You focus on the front sight and the target, and the rear ring takes care of itself. Mounted on the receiver or tang, the aperture also lengthens the sight radius compared with a rear sight out on the barrel, which reduces aiming error.
This guide is an editorial reference built from maker specifications. It does not rank sights by test data, and fit always depends on your exact model and year.
Types of lever-gun peeps
- Receiver sights mount on the side or top of the receiver, close to your eye. They are the most common upgrade and usually the most precise.
- Tang sights mount on the upper tang behind the hammer, often folding down when not in use. They are traditional on Winchester-pattern rifles.
- Barrel-mount peeps replace the rear sight on the barrel. Easier to fit, but they give up the sight-radius advantage.
- Rail-integrated peeps combine a Picatinny rail with a built-in aperture, so you can run irons now and add a red dot or scout scope later.
Quick picks
| Sight | Style | Best for | Skip if |
|---|---|---|---|
| Williams FP receiver sight | Receiver, micrometer-style adjustment | Precise zero; target-style knobs | You want the lowest, simplest profile |
| XS Marlin ghost ring | Receiver ghost ring with white-stripe front | Speed, brush, low light | You want fine target precision |
| Skinner peep sights | Receiver, barrel-mount and rail-integrated | Classic looks, solid steel, many models | You need click adjustments |
| Tang sights (various makers) | Tang-mounted aperture | Winchester-pattern rifles, traditional look | Your rifle lacks tang screw holes |
1. Williams FP receiver sight: the precision choice
Best for: hunters and target shooters who want to dial a zero and come back to it. Skip if: you want the sleekest profile or a sight for a model Williams does not cover.
Williams Gun Sight Company is based in Davison, Michigan. Its FP receiver sight for the Marlin 336 version is offered with and without a ramped front sight set, and Williams describes "internal micrometer adjustments" with "positive internal locks." The target-knob version adds larger knobs for easier adjustment.
The FP's appeal is control. Once your rifle is zeroed, the locks hold the setting, and you can adjust for a different load without guessing.
Ammunition Depot also carries other Williams sights, including fiber-optic and bead front sights for Winchester and Marlin patterns, in its Williams Gun Sight section.
2. XS ghost ring: the fast, rugged choice
Best for: brush hunters, bear-country carry and anyone who values speed. Skip if: you want a small aperture for precise long shots.
XS makes ghost-ring sight sets for Marlin lever guns, listing fit for the 336, 1894, 1895 (.45-70, .450 and .444), 308MX and the Model 9 and .45 Camp Carbine. The sets use a large rear ring with a white-stripe front post. XS notes the stripe is not tritium and does not glow, but reflects visible light. The sights are made to match the existing screw holes on compatible models. One caution from XS: the .35 Remington integral-ramp version will not fit newer Ruger-made Marlins with one-inch hole spacing, so check your rifle.
XS also sells an optic-mount ghost ring for the Marlin 1895, which adds a rail for a red dot or scout scope while keeping the aperture. Browse current XS options in the XS Sight Systems section.
3. Skinner Sights: steel and classic lines
Best for: shooters who want a solid, traditional-looking peep for a lever gun. Skip if: you need click-style adjustments or want a sight from a big-box shelf.
Skinner specializes in aperture sights and says its sights are machined from solid bar stock, aiming for better function, durability and appearance than factory sights. Its lineup includes peep sights, a barrel-mount peep, aperture stems and replacement apertures, and rails with an integrated peep, including a full-length scout rail with peep for the Marlin 1895. Skinner organizes products by rifle brand, with sections for Marlin, Henry, Winchester, Rossi and Browning.
Skinner sights are sold through Skinner directly and other dealers; Ammunition Depot did not list them when this was written.
4. Tang sights
Tang sights are the traditional choice on 1873s, 1892s and 1886s. They put the aperture as close to the eye as it gets and fold down when not needed. The general sights section lists Marble Arms, Williams and XS among its brands. Tang sights require tang screw holes, which some modern rifles have and some do not; a gunsmith can tell you what fits.
Fitting one to your rifle
Marlin 336, 1894 and 1895: the best-supported lever guns for peeps. Receiver sights from Williams and XS, and rails with peeps, are made for these models. Check whether your rifle is a JM, Remington-era or Ruger-era gun, because hole spacing and dimensions can differ.
Henry Big Boy and Side Gate: factory semi-buckhorn sights are standard; look for peeps and rails listed specifically for your Henry model.
Winchester and Miroku reissues: tang sights are the traditional fit; check your model's tang.
Rossi R92 and R95: aftermarket rails and aperture systems exist for these rifles; match the part to your exact model.
Choosing an aperture size
Most peeps accept interchangeable aperture discs or can be run without one. A large ring is faster and more forgiving in dim woods at first and last light. A small aperture sharpens the front sight and can tighten groups in good light. Many lever-gun shooters hunt with a larger aperture and keep a smaller one for range work. Skinner, for example, sells replacement apertures separately.
Zeroing a new peep
A new sight needs a new zero. Start close, adjust in small steps, and confirm at your hunting distance. With a rear aperture, move the rear sight in the direction you want the bullet to go: up to raise the group, right to move it right. Practice with the ammunition you will hunt with, such as a standard .30-30 soft point for a 336.
See the site's optics guide if you are weighing a peep against a red dot or scout scope.

Frequently asked questions
Are peep sights better than buckhorn sights on a lever gun?
For most shooters, yes. Your eye naturally centers the front sight in the aperture, so you only focus on the front sight and target. A receiver peep also lengthens the sight radius compared with a barrel-mounted rear sight, which reduces aiming error.
What is a ghost ring sight?
A ghost ring is an aperture sight with a large, thin ring. It is designed for speed: the ring blurs into a faint circle around the front sight. XS Sights' Marlin ghost rings pair the ring with a white-stripe front post.
Do I need to remove the rear buckhorn sight when I install a peep?
Usually the factory rear sight is removed or folded down so it does not block the view through the aperture. Follow the sight maker's instructions for your model.
Will a peep sight fit my Henry or Marlin without drilling?
Many lever-gun peeps are made to use existing screw holes on specific models. XS, for example, says its Marlin ghost rings match the existing screw holes on compatible models. If your rifle is not drilled and tapped for the sight you want, have a gunsmith do the work.
What aperture size should I use?
Larger apertures are faster and better in low light; smaller ones are more precise in bright light. Many sights let you swap aperture discs, so you can choose by season and use.
