Marble Arms has been making iron sights for well over a century, and the Long Bullseye rear sight is a clever take on the classic peep. Instead of squinting through a single hole, you look through two concentric rings. When everything lines up, your front bead sits dead center in that ring and you know you're on target. The moment the rear sight is off, the front sight drifts out of the center and you instantly know to re-align. It's a fast, forgiving way to aim that works great in low light, for snap shooting, and on moving targets.
This one mounts in a standard 3/8 inch (9.5mm) dovetail, so it drops right into the same slot as the factory rear sight on a lot of lever guns and classic rimfires. It's built from steel with a polished blue finish, so it looks the part on a nice wood-stocked rifle. The outside ring runs 9/16 inch in diameter with a .15 inch inner aperture, giving you that quick center-the-bead sight picture Marble Arms is known for.
The "Long" in the name refers to the 2-3/4 inch blade and extended base, which is the longer of the two adjustable bullseye models. It comes with a six-position step elevator that adjusts in .030 inch increments, so you can fine-tune your elevation without a lot of guesswork. Windage is handled by drifting the sight in the dovetail. Pair it with a bead or traditional blade front sight and you've got a simple, rugged setup that stays dead on in just about any light.
This sight has earned a loyal following on rifles like Marlin 336s, Model 60s, Camp Carbines, and Rossi 92s. Folks consistently praise the quality of the bluing and the way the shape matches up with classic factory sights. If you want a practical iron sight upgrade that's quick to pick up and easy on the eyes, the Long Bullseye is a proven choice.
It's designed to drop into a standard 3/8 inch (9.5mm) dovetail, which is the common rear sight slot on a lot of lever-action and rimfire rifles. It's a popular swap on guns like the Marlin 336, Model 60, and Rossi 92. Measure your existing dovetail before ordering to make sure you've got that nominal 3/8 inch width.
You look through two concentric rings, and your front bead should sit centered in the inner ring when you're on target. If the sight is off, the front bead drifts out of center and tells you to re-align. It gives you a fast, intuitive aiming reference that works well in low light and on moving targets.
Yes. The Long Bullseye comes with a six-position step elevator that adjusts in .030 inch increments, so you can set your elevation and lock it in. Windage is handled by drifting the sight left or right in the dovetail.
The Long model has a 2-3/4 inch blade and an extended base, while the Short model runs about 1-7/8 inches with a shorter base. Both share the same double-ring bullseye peep design and step elevator. The Long version gives you a longer base footprint on the barrel.
