kiväärisähtäimiin

Kiväärisähtäin, often translated as rifle sight, is a device attached to a firearm, specifically a rifle, to aid in aiming. Its primary function is to provide a clear and precise point of reference for the shooter to align with the target. The most common type historically and still prevalent is the iron sight, consisting of two main components: the rear sight and the front sight. The rear sight is typically located towards the shooter's eye and may be adjustable for elevation and windage, allowing for fine-tuning of the shot. The front sight is positioned at the muzzle end of the barrel and presents a post, bead, or other distinct shape. The shooter aligns the front sight within the notch or aperture of the rear sight, and then aligns this combined sight picture with the target.

Modern rifles frequently incorporate optical sights, commonly known as scopes. These devices use lenses to magnify the target, making it appear closer and easier to aim at. Scopes can also feature illuminated reticles, which are crosshairs or other aiming marks that can be lit to improve visibility in low-light conditions. Other specialized sights exist, such as holographic sights and red dot sights, which project a luminous aiming point onto a lens, offering a quick target acquisition capability without the need for precise alignment of two separate components. The choice of sight depends on factors such as the intended use of the rifle, the shooter's preference, and the range at which the target is expected to be.
