Etutähtäimen

Etutähtäin is a term used in firearms terminology, specifically referring to the front sight of a gun. It is one of the two main components of a gun's sighting system, the other being the rear sight. The front sight is typically located at the muzzle end of the barrel, while the rear sight is closer to the shooter's eye. The purpose of the sighting system is to allow the shooter to aim accurately by aligning the front and rear sights with the target.

There are various types of etutähtäin designs. Some are simple post or bead sights, offering a basic aiming point. Others are more complex, featuring adjustable elements that allow for windage (horizontal adjustment) and elevation (vertical adjustment). These adjustable sights are common on rifles and higher-end handguns, providing greater precision for the shooter. The design and visibility of the etutähtäin can significantly impact the speed and accuracy of a shooter's aim, especially in challenging lighting conditions or during rapid firing. Materials used for etutähtäin construction vary, including steel, brass, and modern polymers, with some featuring luminescent inserts for improved low-light visibility.
