Featuring a notch or cut at the rear and a single post at the front or muzzle end of the barrel, open sights are common features on rifles and pistols. Many of the newer open sights have the front and rear sight made of fiber optic material of contrasting colors, that gather light and are easier to see in low light.
Sight picture is the rear sight, front sight and the target all in perfect alignment. Once a hunter masters the sight alignment and the sight picture, it is time to go to a range and sight-in the firearm.
Open Sight Adjustment
After firing a number of shots, check to see where the bullets are grouping. Adjust the sights if the shots are not in the center of the target. Remember that with an open sight, move the rear sight in the direction you want the shots to move on the target.
