Calculating Rear & Front Sight Height Combination

Notch Piece & Screw Set

Bullseye Sight

1. Measure the diameter of the barrel at the point of the rear sight is going to be installed and at the point of the front sight going to be installed (example: 1.0" rear sight and .750" front sight).
2. Divide the diameters by 2 (example: 1.0” / 2 = .500” and .750" / 2 = .375").
3. Check the rear sight height adjustment chart. You want to be about 1/3 up from bottom adjustment. using a sporting rear #67 adjusts from .300" to .510". Total adjustments is .210". Divide .210" / 3 = .070". Add the .070" to the lowest adjustment height (which is .300") and you come up with .370". This is 1/3 up from bottom adjustment.
4. Add the 1/3 adjustment to the center line distance (example: .370" + .500" = .870").
5. Subtract the front sight center line figure from the rear sight height (example: .370" + .500" = .870").
6. You need a combination of front ramp and front sight with the height of .495”. Ramps are measured from the base to the bottom of the dovetails. Front sights are measured from the bottom of the dovetail to the top of the bead.
7. Or you could go with a front sight height of .588". .495" (height need from top of barrel to top of sight) + .093" (which is the depth of the dovetail cut in barrel).

Marble Arms® Folding Rear Sight Chart

The Marble Arms® Sporting Rear Sight is the most recognizable "American Classic" pattern rifle sight. The design dates back to the late 1800s. The Marble Arms ® sporting rear sight became the preferred factory installed, barrel mounted sight of all the major rifle manufacturers. Fast handling, quick firing vintage rifles made by Winchester, Marlin, Remington, and Savage all had Marble Arms® sporting rear sights. We proudly offer the same sporting rear sight as we did 100 years ago. We even still hand-polish each one before it’s blued.

Our sporting rear has the unique double step elevator and the reversible U-shaped and V-shaped notch piece for precision sight-in. The overall sight can be moved up and down with the double step elevator-just like the vintage models. The hand painted enamel diamond on the notch piece instantly draws your eye to the sight notch for quick, instinctive shooting.

The Marble Arms®  Sporting Rear Sight™ is available in flat top, semi-buckhorn or full buckhorn style. We still offer the 1-7/8 inch short carbine model and the 2-3/4 inch full rifle model. (Measuring from center of dovetail to front of face.) The authentic Marble Arms ® Sporting Rear Sight is available in over 20 various heights from .275 inches to .630 inches.

How to Use Table Above-Suppose a rifle, having a sighting radius of 24” between front sight and receiver sight, shoots 6” high at 100 yards, even with the rear sight adjusted as low as possible. Remove front sight and measure overall height, preferable with a micrometer. This might be .410”, such as a Marble No. 41MR. Reference to columns for 24” and 6” on table above will show a necessary correction of .040”. This would mean a new, higher front sight (with an overall height of .410” plus .040” for a correction height of .450”) such as a Marble No. 45MR, should be installed.
Sighting in should be done with a bench rest or prone with a sand bag or other rest for the rifle. Do not put rifle barrel or forearm directly on solid surface, but put the back of your hand or wrist on the rest and hold forearm of the rifle securely in your hand with approximately the same tightness of grip you would use when shooting at running game. If the firearm or barrel is rested directly on the sand bag or rest, the rifle will shoot higher than when held firmly while shooting at game as more “muzzle flip” will occur.

Sporting Rear Sights

Marble Arms® has been making folding rear sights for almost 100 years. They flatten on top of a gun barrel to allow the use of a Tang Peep sight or scope without interference. Our Folding Leaf Rear Sight is available as windage adjustable or drift adjustable. This unique feature allows you to precision adjust your sight with a small screwdriver or a hammer. The height adjustable notch piece has both U-shaped and V-shaped centers. You can remove and reverse your notch piece with a small screwdriver. The hand painted enamel diamond draws the eye to the center of the notch for lightening quick sight alignment. Marble Arms ® Folding Leaf Rear Sights are machined from solid steel and are available in traditional flat-top style. We make these fine sights in four heights from .360 inches to .620 inches.

The Step Elevator controls the height adjustment of the rear sights just like the vintage models. Available for 1-7/8 inch and 2-3/4 inch rear sights. The double step design assures sturdiness. Thumb button has been added for easy adjustment.

Barrel-mounted, dovetail Marble Arms®  Bullseye sight gets you on target fast with perfect alignment for improved accuracy. Steel, double-ring peep design ensures consistent sight alignment and helps improve shooting form. The moment the rear sight is misaligned, the front sight drifts out of the center ring, telling the shooter to re-align. Replaces standard 3⁄8" dovetail rear sights on many rifles. For use with bead-type or traditional blade front sights. Adjustable models are available with a short or long base and six-position step elevator that’s adjustable in .030" increments for precise elevation settings. Fixed model features the same Marble Arms® Bullseye peep design but without the extended base and is not elevation adjustable. All models are drift adjustable for windage. May require minor fitting.
