The side turret allow you to adjust for windage (left and right). The top turret allows you to adjust for elevation (up and down). In the image above, you can see that there are two 'turrets' that allow you to adjust the scope. Larger lenses typically allow more light in but the quality of the optics plays a big part in the quality of the image through the scope. This means that the front lens (the 'objective' lens) is 40mm in diameter. When looking at scope specs, you'll sometimes see them listed as a 6-18 x 40. For example, a scope may have a 3-9 or a 6-24 range of magnification. Variable scopes generally have a limited range of magnification. While some scopes have a fixed power (2x, 4x.) many are variable. Magnifications between 2x and 24x are common. Telescopic sights offer magnification of the target. Many allow you to change the front bead/post.įor targets that are either very small or very far away, telescopic sights are used. The next two photos show the front sight. For hunting, a larger aperture would allow quicker target acquisition. For precision shooting, you'd select a smaller aperture.
The rear aperture is typically selected for the type of shooting you'll be doing. With practice, you'll learn to center the front sight (focal point) in the fuzzy rear aperture. Like open sights, the two sights won't be in clear focus. You look through the 'aperture' and center the bead on the front sight in the aperture. The next two images show the rear part of the sight. After you learn to use them, these tend to be a bit easier to use than open sights. It's from my Air Rifle web site.Ĭlick HERE to make this applet fill this window.Īnother type of sight is the 'peep' sight. The demo below provides a bit more information on the use of these sights. They also take a bit of practice because at no point will both sights and the target be in sharp focus (your eyes can't focus on three different distances at once.
These can be accurate but if your eyesight isn't great, they may be difficult to use. For these, you align the front and rear sights on the target. It's not the most accurate type of iron sight but it works well enough for most types of shooting that you'll do with a shotgun.įor guns that require a bit more precise aiming, you may find the type of sight seen below. You simply look down the top ridge of the shotgun and put the bead on the target. It's a round bead at the muzzle end of the barrel. The simplest is the type found on many shotguns. Below, you will see descriptions of various sights and the pros/cons associated with each type of sight. The most basic sights have one point on the end of the barrel and one closer to the rear of the gun that are aligned with each other and the target. To do that, you need some sort of sighting device on the gun. When using most types of guns, you need to be able to accurately aim the gun at the target.
