The Marble Arms improved peep tang sight is adjustable for windage and elevation. The adjustments are micrometer precise. Each firm detent click equals four-tenths of an inch movement at 100 yards.
We stock sights for Stevens target rifles only - Marbles sights for other rifles are available from other suppliers. Hole spacing is 1.485" and screws with 5-40 threads are included along with one 1/2" eyepiece with a .055" aperture. These sights will fit original Stevens Favorite, Model 44, Model 44 1/2 and our CPA 44 1/2 rifles.
The improved peep sight features interchangeable staffs which are available in three heights:
Short: height adjusts from .50" to .75" above bore height, suitable for front sights up to .375" on Favorite rifles with muzzle diameter about .65"
Standard: height adjusts from .75" to 1.20" above bore height, suitable for taller front sights on Favorites and front sights up to .62" on Model 44, 44 1/2 and CPA rifles with muzzle diameter about 1".
Mid Range: height adjusts from 1.20" to 2.0" above bore height, suitable for distances 400-700 yards in common configurations.
To be sure you are getting the correct rear sight, use the following formula to find the height of your front sight above the bore:
(muzzle diameter / 2) - .080" + front sight height
If you are shooting at longer distances, you may need extra height in your rear sight to compensate for the bullet's drop
